根据创建日期选择文件

Question

我有一个名为 myclientcard 的文件夹，它在该子文件夹中有 69 个子文件夹，我们有许多子文件夹，它必须转到错误文件夹，在错误文件夹中它有许多 txt 文件，所以我想要那些文本文件的内容使用日期格式 17/01/2019 到 24/01/2019 指定的所有 69 个文件夹内的错误并将其转换为 excel 文件

import os
import numpy as np
from os import listdir
from os.path import join
import pandas as pd
from pandas import ExcelWriter
from pandas import ExcelFile
mypath = "D:\myclientcard"
files = [join(mypath,f) for f in listdir(mypath) if '.txt' not in f]
for file in files:
    path = file
    filename =[join(path,f) for f in listdir(path) if 'ERROR' in f]
    #print(filename)
    for text_file_path in filename:
        file_path = text_file_path
        textfiles = [join(file_path,f) for f in listdir(file_path) if '.txt' in f]
        for files in textfiles:
                reading_files = open(files,'r')
                read = reading_files.read()
                writting_files = open('result.txt','a')
                wr = writting_files.write(read)
                read_files = pd.read_csv('result.txt',delim_whitespace='')
                writer = ExcelWriter('output.xlsx')
                read_files.to_excel(writer,'Sheet1',index=false)
                writer.save()
                reading_files.close()
                writting_files.close()

使用来自here 和here 的答案。假设您在 Windows 平台上。

import os
import numpy as np
from os import listdir
from os.path import join
# Importing datetime module
from datetime import datetime as dt
import pandas as pd
from pandas import ExcelWriter
from pandas import ExcelFile
mypath = "D:\myclientcard"

# Add start date here
start_date = dt.strptime('17/01/2019', '%d/%m/%Y')
# Add end date here
end_date = dt.strptime('24/01/2019', '%d/%m/%Y')
files = [join(mypath,f) for f in listdir(mypath) if '.txt' not in f]
for file in files:
    path = file
    filename =[join(path,f) for f in listdir(path) if 'ERROR' in f]
    #print(filename)
    for text_file_path in filename:
        file_path = text_file_path
        textfiles = [join(file_path,f) for f in listdir(file_path) if '.txt' in f]
        # Filtering on the basis of date
        textfiles = [f for f in textfiles if ((os.path.getctime(f) >= start_date) and (os.path.getctime(f) <= end_date))]
        for files in textfiles:
                reading_files = open(files,'r')
                read = reading_files.read()
                writting_files = open('result.txt','a')
                wr = writting_files.write(read)
                read_files = pd.read_csv('result.txt',delim_whitespace='')
                writer = ExcelWriter('output.xlsx')
                read_files.to_excel(writer,'Sheet1',index=false)
                writer.save()
                reading_files.close()
                writting_files.close()

另外，请考虑优化您的代码。也可以试试os.walk，它有时会很有用！
