无法相应地打印结果并将相同的结果写入 csv 文件

Question

我正在尝试根据字典中的category name 解析一些categories 的值。我选择从这本字典中解析的类别名称现在是Interior Features 和Spaces and Amenities。以下脚本可以解析它们，但是当我尝试打印它们时，该输出的对齐变得混乱，当我编写它们时，这显然会在 csv 文件中产生类似的影响。

如何打印结果并以正确的方式将其写入 csv 文件？

以下内容供您参考：

[{'categoryGroupName': 'Interior Features', 'categories': [{'categoryName': 'Bedrooms', 'categoryFacts': [{'factLabel': 'Beds', 'factValue': '3'}, {'factLabel': 'Master bedroom location', 'factValue': 'Main'}]}, {'categoryName': 'Kitchen', 'categoryFacts': [{'factLabel': 'Kitchen location', 'factValue': 'Main'}]}, {'categoryName': 'Other Rooms', 'categoryFacts': [{'factLabel': 'Dining room location', 'factValue': 'Main'}, {'factLabel': 'Living room location', 'factValue': 'Main'}, {'factLabel': 'Utility room location', 'factValue': 'Lower'}]}, {'categoryName': 'Heating and Cooling', 'categoryFacts': [{'factLabel': 'Heating', 'factValue': 'Forced air'}, {'factLabel': 'Heating', 'factValue': 'Gas'}, {'factLabel': 'Heating and cooling', 'factValue': '90%+ High Efficiency, Forced Air'}]}, {'categoryName': 'Basement', 'categoryFacts': [{'factLabel': None, 'factValue': 'Partially finished'}, {'factLabel': None, 'factValue': '900 sqft basement'}, {'factLabel': 'Basement', 'factValue': 'Partially Finished'}]}, {'categoryName': 'Attic', 'categoryFacts': [{'factLabel': None, 'factValue': 'Attic'}]}, {'categoryName': 'Appliances', 'categoryFacts': [{'factLabel': 'Appliances included', 'factValue': 'Dishwasher, Dryer, Microwave, Range / Oven, Refrigerator, Washer'}, {'factLabel': 'Appliances that stay', 'factValue': 'Range/Oven, Dishwasher, Refrigerator, Washer, Dryer'}]}, {'categoryName': 'Flooring', 'categoryFacts': [{'factLabel': 'Floor size', 'factValue': '2,070 sqft'}, {'factLabel': 'Flooring', 'factValue': 'Carpet, Hardwood, Tile'}, {'factLabel': 'Floor covering', 'factValue': 'Hardwood, Laminate, Wall to Wall Carpet'}]}, {'categoryName': 'Other Interior Features', 'categoryFacts': [{'factLabel': 'Addition size', 'factValue': '900'}, {'factLabel': None, 'factValue': 'Fireplace'}, {'factLabel': None, 'factValue': 'Ceiling Fan'}, {'factLabel': 'Features', 'factValue': 'Dbl Pane/Storm Windw, Dining Room, Security System, Ceiling Fan(s), Hot Tub/Spa'}]}]}, {'categoryGroupName': 'Building', 'categories': [{'categoryName': 'Other Building Features', 'categoryFacts': [{'factLabel': 'Building info', 'factValue': 'Built On Lot'}]}]}, {'categoryGroupName': 'Spaces and Amenities', 'categories': [{'categoryName': 'Size', 'categoryFacts': [{'factLabel': 'Unit count', 'factValue': '1'}]}, {'categoryName': 'Spaces', 'categoryFacts': [{'factLabel': None, 'factValue': 'Hot Tub/Spa'}]}, {'categoryName': 'Amenities', 'categoryFacts': [{'factLabel': None, 'factValue': 'Security System'}]}]}, {'categoryGroupName': 'Construction', 'categories': [{'categoryName': 'Type and Style', 'categoryFacts': [{'factLabel': 'Structure type', 'factValue': 'Craftsman'}, {'factLabel': None, 'factValue': 'Single Family'}, {'factLabel': 'Architecture', 'factValue': 'Craftsman'}, {'factLabel': 'Entrance level', 'factValue': 'Main'}, {'factLabel': 'Style', 'factValue': '16 -

我尝试过的脚本：

desc = [{'categoryGroupName': 'Interior Features', 'categories': [{'categoryName': 'Bedrooms', 'categoryFacts': [{'factLabel': 'Beds', 'factValue': '3'}, {'factLabel': 'Master bedroom location', 'factValue': 'Main'}]}, {'categoryName': 'Kitchen', 'categoryFacts': [{'factLabel': 'Kitchen location', 'factValue': 'Main'}]}, {'categoryName': 'Other Rooms', 'categoryFacts': [{'factLabel': 'Dining room location', 'factValue': 'Main'}, {'factLabel': 'Living room location', 'factValue': 'Main'}, {'factLabel': 'Utility room location', 'factValue': 'Lower'}]}, {'categoryName': 'Heating and Cooling', 'categoryFacts': [{'factLabel': 'Heating', 'factValue': 'Forced air'}, {'factLabel': 'Heating', 'factValue': 'Gas'}, {'factLabel': 'Heating and cooling', 'factValue': '90%+ High Efficiency, Forced Air'}]}, {'categoryName': 'Basement', 'categoryFacts': [{'factLabel': None, 'factValue': 'Partially finished'}, {'factLabel': None, 'factValue': '900 sqft basement'}, {'factLabel': 'Basement', 'factValue': 'Partially Finished'}]}, {'categoryName': 'Attic', 'categoryFacts': [{'factLabel': None, 'factValue': 'Attic'}]}, {'categoryName': 'Appliances', 'categoryFacts': [{'factLabel': 'Appliances included', 'factValue': 'Dishwasher, Dryer, Microwave, Range / Oven, Refrigerator, Washer'}, {'factLabel': 'Appliances that stay', 'factValue': 'Range/Oven, Dishwasher, Refrigerator, Washer, Dryer'}]}, {'categoryName': 'Flooring', 'categoryFacts': [{'factLabel': 'Floor size', 'factValue': '2,070 sqft'}, {'factLabel': 'Flooring', 'factValue': 'Carpet, Hardwood, Tile'}, {'factLabel': 'Floor covering', 'factValue': 'Hardwood, Laminate, Wall to Wall Carpet'}]}, {'categoryName': 'Other Interior Features', 'categoryFacts': [{'factLabel': 'Addition size', 'factValue': '900'}, {'factLabel': None, 'factValue': 'Fireplace'}, {'factLabel': None, 'factValue': 'Ceiling Fan'}, {'factLabel': 'Features', 'factValue': 'Dbl Pane/Storm Windw, Dining Room, Security System, Ceiling Fan(s), Hot Tub/Spa'}]}]}, {'categoryGroupName': 'Building', 'categories': [{'categoryName': 'Other Building Features', 'categoryFacts': [{'factLabel': 'Building info', 'factValue': 'Built On Lot'}]}]}, {'categoryGroupName': 'Spaces and Amenities', 'categories': [{'categoryName': 'Size', 'categoryFacts': [{'factLabel': 'Unit count', 'factValue': '1'}]}, {'categoryName': 'Spaces', 'categoryFacts': [{'factLabel': None, 'factValue': 'Hot Tub/Spa'}]}, {'categoryName': 'Amenities', 'categoryFacts': [{'factLabel': None, 'factValue': 'Security System'}]}]}, {'categoryGroupName': 'Construction', 'categories': [{'categoryName': 'Type and Style', 'categoryFacts': [{'factLabel': 'Structure type', 'factValue': 'Craftsman'}, {'factLabel': None, 'factValue': 'Single Family'}, {'factLabel': 'Architecture', 'factValue': 'Craftsman'}, {'factLabel': 'Entrance level', 'factValue': 'Main'}, {'factLabel': 'Style', 'factValue': '16 -

name = "property in somewhere"

for elem in desc:

    if elem['categoryGroupName']=='Interior Features':
        interior_features = {curr['factLabel']: curr['factValue'] for i in elem['categories'] for curr in i['categoryFacts']}
        interior_features = str(interior_features).replace("{","").replace("}","").replace("'","")
    else:
        interior_features = ""

    if elem['categoryGroupName']=='Spaces and Amenities':
        space_amenities = {curr['factLabel']: curr['factValue'] for i in elem['categories'] for curr in i['categoryFacts']}
        space_amenities = str(space_amenities).replace("{","").replace("}","").replace("'","")
    else:
        space_amenities = ""

    print(name,interior_features,space_amenities)

我得到的结果：

property in somewhere Beds: 3, Master bedroom location: Main, Kitchen location: Main, Dining room location: Main, Living room location: Main, Utility room location: Lower, Heating: Gas, Heating and cooling: 90%+ High Efficiency, Forced Air, None: Ceiling Fan, Basement: Partially Finished, Appliances included: Dishwasher, Dryer, Microwave, Range / Oven, Refrigerator, Washer, Appliances that stay: Range/Oven, Dishwasher, Refrigerator, Washer, Dryer, Floor size: 2,070 sqft, Flooring: Carpet, Hardwood, Tile, Floor covering: Hardwood, Laminate, Wall to Wall Carpet, Addition size: 900, Features: Dbl Pane/Storm Windw, Dining Room, Security System, Ceiling Fan(s), Hot Tub/Spa 
property in somewhere  
property in somewhere  Unit count: 1, None: Security System
property in somewhere  
property in somewhere  
property in somewhere  
property in somewhere  
property in somewhere  
property in somewhere  
property in somewhere

在上面的输出中你可以看到这行property in somewhere 已经被打印了好几次，而它应该被打印一次。这行Unit count: 1, None: Security System 应该在第三列，而它被放置了一些不需要的区域。

底线是上面的脚本应该打印一次结果，但由于 for 循环，它会打印多次。

预期输出（在此处粘贴变量名称而不是它们的值，以使您了解对齐方式）。更清楚一点 - b 行、c 行等没有结果。结果应打印一次，并仅限于 A1 行、B1 行和 C1 行。期间。

Answer 1

如果我理解正确，目标是从desc 中的项目中获取某些值。每个值可能出现一次或根本不出现 - 在这种情况下，结果应该是“N/A”。因此，您可以使用具有 N/A 默认值的字典，然后将它们替换为在 desc 列表中找到的值。

desc = [{'categoryGroupName': 'Interior Features', 'categories': [{'categoryName': 'Bedrooms', 'categoryFacts': [{'factLabel': 'Beds', 'factValue': '3'}, {'factLabel': 'Master bedroom location', 'factValue': 'Main'}]}, {'categoryName': 'Kitchen', 'categoryFacts': [{'factLabel': 'Kitchen location', 'factValue': 'Main'}]}, {'categoryName': 'Other Rooms', 'categoryFacts': [{'factLabel': 'Dining room location', 'factValue': 'Main'}, {'factLabel': 'Living room location', 'factValue': 'Main'}, {'factLabel': 'Utility room location', 'factValue': 'Lower'}]}, {'categoryName': 'Heating and Cooling', 'categoryFacts': [{'factLabel': 'Heating', 'factValue': 'Forced air'}, {'factLabel': 'Heating', 'factValue': 'Gas'}, {'factLabel': 'Heating and cooling', 'factValue': '90%+ High Efficiency, Forced Air'}]}, {'categoryName': 'Basement', 'categoryFacts': [{'factLabel': None, 'factValue': 'Partially finished'}, {'factLabel': None, 'factValue': '900 sqft basement'}, {'factLabel': 'Basement', 'factValue': 'Partially Finished'}]}, {'categoryName': 'Attic', 'categoryFacts': [{'factLabel': None, 'factValue': 'Attic'}]}, {'categoryName': 'Appliances', 'categoryFacts': [{'factLabel': 'Appliances included', 'factValue': 'Dishwasher, Dryer, Microwave, Range / Oven, Refrigerator, Washer'}, {'factLabel': 'Appliances that stay', 'factValue': 'Range/Oven, Dishwasher, Refrigerator, Washer, Dryer'}]}, {'categoryName': 'Flooring', 'categoryFacts': [{'factLabel': 'Floor size', 'factValue': '2,070 sqft'}, {'factLabel': 'Flooring', 'factValue': 'Carpet, Hardwood, Tile'}, {'factLabel': 'Floor covering', 'factValue': 'Hardwood, Laminate, Wall to Wall Carpet'}]}, {'categoryName': 'Other Interior Features', 'categoryFacts': [{'factLabel': 'Addition size', 'factValue': '900'}, {'factLabel': None, 'factValue': 'Fireplace'}, {'factLabel': None, 'factValue': 'Ceiling Fan'}, {'factLabel': 'Features', 'factValue': 'Dbl Pane/Storm Windw, Dining Room, Security System, Ceiling Fan(s), Hot Tub/Spa'}]}]}, {'categoryGroupName': 'Building', 'categories': [{'categoryName': 'Other Building Features', 'categoryFacts': [{'factLabel': 'Building info', 'factValue': 'Built On Lot'}]}]}, {'categoryGroupName': 'Spaces and Amenities', 'categories': [{'categoryName': 'Size', 'categoryFacts': [{'factLabel': 'Unit count', 'factValue': '1'}]}, {'categoryName': 'Spaces', 'categoryFacts': [{'factLabel': None, 'factValue': 'Hot Tub/Spa'}]}, {'categoryName': 'Amenities', 'categoryFacts': [{'factLabel': None, 'factValue': 'Security System'}]}]}, {'categoryGroupName': 'Construction', 'categories': [{'categoryName': 'Type and Style', 'categoryFacts': [{'factLabel': 'Structure type', 'factValue': 'Craftsman'}, {'factLabel': None, 'factValue': 'Single Family'}, {'factLabel': 'Architecture', 'factValue': 'Craftsman'}, {'factLabel': 'Entrance level', 'factValue': 'Main'}, {'factLabel': 'Style', 'factValue': '16 -

name = "property in somewhere"
rows = {'name': name, 'interior_features':'N/A', 'space_amenities':'N/A', 'imaginary_stuff':'N/A'}

for elem in desc:
    if elem['categoryGroupName']=='Interior Features':
        interior_features = {curr['factLabel']: curr['factValue'] for i in elem['categories'] for curr in i['categoryFacts']}
        interior_features = str(interior_features).replace("{","").replace("}","").replace("'","")
        rows['interior_features'] = interior_features

    if elem['categoryGroupName']=='Imaginary Stuff':
        imaginary_stuff = {curr['factLabel']: curr['factValue'] for i in elem['categories'] for curr in i['categoryFacts']}
        imaginary_stuff = str(imaginary_stuff).replace("{","").replace("}","").replace("'","")

print(rows)

但是，如果一个值出现不止一次，上面的代码可能会出现问题，因为它只会存储最后一个值。在这种情况下，我们可以使用空列表作为 rows 字典的值。然后附加在desc 列表中找到的值。最后，如果一个列表有值，则将它们加入一个字符串，如果没有，则将空列表替换为“N/A”。

desc = [{'categoryGroupName': 'Interior Features', 'categories': [{'categoryName': 'Bedrooms', 'categoryFacts': [{'factLabel': 'Beds', 'factValue': '3'}, {'factLabel': 'Master bedroom location', 'factValue': 'Main'}]}, {'categoryName': 'Kitchen', 'categoryFacts': [{'factLabel': 'Kitchen location', 'factValue': 'Main'}]}, {'categoryName': 'Other Rooms', 'categoryFacts': [{'factLabel': 'Dining room location', 'factValue': 'Main'}, {'factLabel': 'Living room location', 'factValue': 'Main'}, {'factLabel': 'Utility room location', 'factValue': 'Lower'}]}, {'categoryName': 'Heating and Cooling', 'categoryFacts': [{'factLabel': 'Heating', 'factValue': 'Forced air'}, {'factLabel': 'Heating', 'factValue': 'Gas'}, {'factLabel': 'Heating and cooling', 'factValue': '90%+ High Efficiency, Forced Air'}]}, {'categoryName': 'Basement', 'categoryFacts': [{'factLabel': None, 'factValue': 'Partially finished'}, {'factLabel': None, 'factValue': '900 sqft basement'}, {'factLabel': 'Basement', 'factValue': 'Partially Finished'}]}, {'categoryName': 'Attic', 'categoryFacts': [{'factLabel': None, 'factValue': 'Attic'}]}, {'categoryName': 'Appliances', 'categoryFacts': [{'factLabel': 'Appliances included', 'factValue': 'Dishwasher, Dryer, Microwave, Range / Oven, Refrigerator, Washer'}, {'factLabel': 'Appliances that stay', 'factValue': 'Range/Oven, Dishwasher, Refrigerator, Washer, Dryer'}]}, {'categoryName': 'Flooring', 'categoryFacts': [{'factLabel': 'Floor size', 'factValue': '2,070 sqft'}, {'factLabel': 'Flooring', 'factValue': 'Carpet, Hardwood, Tile'}, {'factLabel': 'Floor covering', 'factValue': 'Hardwood, Laminate, Wall to Wall Carpet'}]}, {'categoryName': 'Other Interior Features', 'categoryFacts': [{'factLabel': 'Addition size', 'factValue': '900'}, {'factLabel': None, 'factValue': 'Fireplace'}, {'factLabel': None, 'factValue': 'Ceiling Fan'}, {'factLabel': 'Features', 'factValue': 'Dbl Pane/Storm Windw, Dining Room, Security System, Ceiling Fan(s), Hot Tub/Spa'}]}]}, {'categoryGroupName': 'Building', 'categories': [{'categoryName': 'Other Building Features', 'categoryFacts': [{'factLabel': 'Building info', 'factValue': 'Built On Lot'}]}]}, {'categoryGroupName': 'Spaces and Amenities', 'categories': [{'categoryName': 'Size', 'categoryFacts': [{'factLabel': 'Unit count', 'factValue': '1'}]}, {'categoryName': 'Spaces', 'categoryFacts': [{'factLabel': None, 'factValue': 'Hot Tub/Spa'}]}, {'categoryName': 'Amenities', 'categoryFacts': [{'factLabel': None, 'factValue': 'Security System'}]}]}, {'categoryGroupName': 'Construction', 'categories': [{'categoryName': 'Type and Style', 'categoryFacts': [{'factLabel': 'Structure type', 'factValue': 'Craftsman'}, {'factLabel': None, 'factValue': 'Single Family'}, {'factLabel': 'Architecture', 'factValue': 'Craftsman'}, {'factLabel': 'Entrance level', 'factValue': 'Main'}, {'factLabel': 'Style', 'factValue': '16 -

如果您希望将rows 字典转换为列表，您可以使用rows.values()。您还可以使用csv.DictWriter()，这样您就可以将结果写入文件，而无需将其转换为列表。

import csv

with open('file.csv', 'w', encoding='utf-8', newline='') as f:
    w = csv.DictWriter(f, rows.keys())
    w.writeheader()
    w.writerow(rows)

Answer 2

您的代码的两个模块：

(1) 根据每列的最大宽度左对齐每个字段

(2) 不要打印与所需类别不匹配的类别（即返回空特征）

def features(elem):
    " Gets features (interior and space) for current element "
    if elem['categoryGroupName']=='Interior Features':
            interior_features = {curr['factLabel']: curr['factValue'] for i in elem['categories'] for curr in i['categoryFacts']}
            interior_features = str(interior_features).replace("{","").replace("}","").replace("'","")
    else:
        interior_features = ""

    if elem['categoryGroupName']=='Spaces and Amenities':
            space_amenities = {curr['factLabel']: curr['factValue'] for i in elem['categories'] for curr in i['categoryFacts']}
            space_amenities = str(space_amenities).replace("{","").replace("}","").replace("'","")
    else:
        space_amenities = ""

    return interior_features, space_amenities

def format_data(row, col_widths):
    " Format row data so it has the right column width "
    # align based upon max width of each column
    # columns are tab separated so this can act as a CSV file
    return "/t".join(word.ljust(col_widths[i]) for i, word in enumerate(row))

# Widths to use for fields
feature_widths = [list(map(len, features(elem))) for elem in desc]
field0_max = len('property in somewhere')
field1_max = max(i[0] for i in feature_widths)
field2_max = max(i[1] for i in feature_widths)
col_widths = [field0_max+2, field1_max + 2, field2_max+2]

# Print header
with open('test.txt', 'w') as txtfile:
    # Write header
    row = ["property in somewhere", 'interior_features', 'space_amenities']
    s = format_data(row, col_widths)
    print(s)  # to stdout
    txtfile.write(s) # to file
    txtfile.write("\n")

    for elem in desc:
        interior_features, space_amenities = features(elem)
        if interior_features or space_amenities: # only write elements with features
            row = ["property in somewhere", interior_features, space_amenities]
            s = format_data(row, col_widths)
            print(s)  # to stdout
            txtfile.write(s) # to file
            txtfile.write("\n")

输出
