使用用户输入修复文件路径以创建文件搜索功能答案

【问题标题】：Fixing File path with user input to create search for file function使用用户输入修复文件路径以创建文件搜索功能
【发布时间】：2022-01-17 00:47:05
【问题描述】：

我有一堆名为 (modelnumber)_filter 的 CSV 文件。系统会询问用户他们正在搜索的型号，所以
示例用户输入：“1.3C-H4SL-D1” 那么文件路径将被加载：

“C:\Users\ADMIN-SURV\Desktop\data_pull\1.3C-H4SL-D1_filter.csv”

EX CSV

然后，还将使用该输入创建一个新文件：

“C:\Users\ADMIN-SURV\Desktop\data_pull\1.3C-H4SL-D1.txt”

这是我的代码。

import csv
import re
import sys

new_file = input("What is the camera model? **Use Exact Casing and Symbols**")
file_path = "C:\\Users\\ADMIN-SURV\\Desktop\\data_pull\\filter_results\\"
end_path = file_path + new_file + ".txt"
print(end_path)

sys.stdout = open(end_path, 'x')
with open("C:\\Users\\ADMIN-SURV\\Desktop\\data_pull\\" + new_file + "_filter.csv") as fid:
    print(fid)
    input_file = csv.reader(fid)
    for row in input_file:
        if len(row) >= 4:
            if row[0] == 'File name':
                # skip the header row
                continue
            # m = re.match(r".*(.* [0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3})", row[3])
            m = re.match(r'.*(.* [0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3})', row[3])
            if m:
                print(m.group(1))
            else:
                print(row[3])

sys.stdout.close()

到目前为止，当我运行此代码时，我收到以下错误

Traceback（最近一次调用最后一次）：文件“C:\Users\ADMIN-SURV\PycharmProjects\pdf_scraping\test_file.,py”，第 28 行，在使用 open("C:\Users\ADMIN-SURV\Desktop\data_pull\" + new_file + "_filter.csv") 作为fid： FileNotFoundError：[Errno 2] 没有这样的文件或目录：'C:\Users\ADMIN-SURV\Desktop\data_pull\1.3C-H4SL-D1_filter.csv'

CSV 文件已经存在，应该可以通过用户输入找到。应使用用户输入创建 .TXT 文件。

【问题讨论】：

您正在使用/运行的确切 Python 版本是什么？
@MaXiMkA Python 3.10.0
我复制了你的代码示例，有 26 行。您的错误是第 28 行。顺便说一句，它在 3.8.0 上使用虚拟 .csv 执行
@MaXiMkA 是的，我从这里的代码中删除了一些行，因为它有很多 cmets。什么是虚拟 csv 文件？它应该只在已经存在的情况下才有效。
你没有提到 .csv 文件的内容，所以我在前 2 列中创建了一个 1,2,3,4 和 a,b,c,d 的虚拟文件。

标签： python python-3.x csv automation

【解决方案1】：

使用 Python 3.8.0 运行它，结果是 ../filter_results 中没有扩展名的文件。我将其更改为 .txt，这是它的内容：

<_io.textiowrapper name="C:\Users\maxim\PycharmProjects\FB_Books\data_pull\1.3C-H4SL-D1_filter.csv" mode="r" encoding="cp1252">

【讨论】：

我不太关注

【解决方案2】：

你得到的原因

<_io.TextIOWrapper name='C:\Users\maxim\PycharmProjects\FB_Books\data_pull\1.3C-H4SL-D1_filter.csv' mode='r' encoding='cp1252'>

是因为sys.stdout = open(end_path, 'x')。

open(end_path, 'x') 返回

<_io.TextIOWrapper name='C:\Users\maxim\PycharmProjects\FB_Books\data_pull\1.3C-H4SL-D1_filter.csv' mode='r' encoding='cp1252'>

所以我们要稍微清理一下逻辑。我们将使用'x'参数打开新文件（意味着如果没有创建文件，它将创建并写入。但是，如果它已经创建，则不允许打开和覆盖它）

然后使用您的逻辑，我们将 ip 地址写入该文件。

import csv
import re
import sys

new_file = input("What is the camera model? **Use Exact Casing and Symbols**")
file_path = "C:\\Users\\ADMIN-SURV\\Desktop\\data_pull\\filter_results\\"
end_path = file_path + new_file + ".txt"
print(end_path)

output_txt_file = open(end_path, 'x')
with open("C:\\Users\\ADMIN-SURV\\Desktop\\data_pull\\" + new_file + "_filter.csv") as fid:
    print(fid)
    input_file = csv.reader(fid)
    for row in input_file:
        if len(row) >= 4:
            if row[0] == 'File name':
                # skip the header row
                continue
            # m = re.match(r".*(.* [0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3})", row[3])
            m = re.match(r'.*(.* [0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3})', row[3])
            if m:
                print(m.group(1).strip())
                output_txt_file.write(m.group(1).strip() + '\n')
                
            else:
                print(row[3])

output_txt_file.close()

【讨论】：

这很有效，谢谢！通过电子邮件发送进一步的通信
如何从这一行中提取整数“481”并打印它而不是整个字符串？ “检测：不支持 481 1.3C-H4SL-D1(1866954) Avigilon (ONVIF) 1.3C-H4SL-D1 Unknown” 每一行都有不同的数字，而不是所有的“481”，所以代码会有能够提取的不仅仅是“481”
感谢您的澄清。感觉end_path属性不对，但是没时间进一步调试。
