python文件命中用户警告:重复名称

Question

我有一个python脚本，它排除了文件夹，并将其余的压缩到zip文件中。但是，我的脚本将所有文件压缩在同一目录级别上。

它给出了以下错误：

C:\Program Files\Python39\lib\zipfile.py:1505: UserWarning: Duplicate name: '1.txt'
  return self._open_to_write(zinfo, force_zip64=force_zip64)
C:\Program Files\Python39\lib\zipfile.py:1505: UserWarning: Duplicate name: '2.txt'
  return self._open_to_write(zinfo, force_zip64=force_zip64)

要压缩的文件夹结构。

-test
 -file1
   -1.txt
   -2.txt
 -file2
   -1.txt
   -2.txt
 -dump
 -file3

我的python脚本

import os
from zipfile import ZipFile
from datetime import date
from os.path import basename

# format the dd/mm/y 
today = date.today()
todayDate = today.strftime("%d-%m-%y")

# path to zip
pathZip = "C:\\PY\\Project\\Self\\python-zip\\test"
# get the final forler name
forlderToZip = basename(pathZip)

# format the zip file name
zipFileName = todayDate + " " + forlderToZip + ".zip"
# create a ZipFile object
zipObj = ZipFile(zipFileName, "w")
# exclude the folder to be zip
exclude_folder = "dump"

print("Zip start...")
for dirname, subdirs, files in os.walk(pathZip):
    if exclude_folder in subdirs:
        subdirs.remove(exclude_folder)
    # Add empty folder to zip
    zipObj.write(dirname)
    for filename in files:
        # create complete filepath of file in directory
        filePath = os.path.join(dirname, filename)
        # Add file to zip
        zipObj.write(filePath,basename(filePath))
        print("Zip " + filePath)
# close the Zip File
zipObj.close()
print("Zip done !")

重复名称警告来自相同名称的输入目录文件，所有这些文件都被写入输出zip的同一个位置。下面的内容会被覆盖，您将在zip中留下两个文本文件。

-Output Zip
    -1.txt
    -1.txt
    -2.txt
    -2.txt

弧名参数在下面展开，以保留原始目录的嵌套结构。arg在写入zip时修改文件的名称和位置。“如果继续”用于跳过具有“转储”路径的子文件。

import os
from zipfile import ZipFile

path_to_dir = ''
path_to_zip = ''

output_zip = ZipFile(path_to_zip, "w")
for dirpath, dirnames, filenames in os.walk(path_to_dir):
    if 'dump' in dirpath:
        continue
    for f in filenames:
        outpath = os.path.join(dirpath, f)
        arcname = outpath[len(path_to_dir):].lstrip(os.sep)
        output_zip.write(outpath, arcname)
output_zip.close()

-Output Zip
    -folder1
        -1.txt
        -2.txt
    -folder2
        -1.txt
        -2.txt

或者，从原始目录重命名文件，使它们是唯一的。一种方法是替换弧名路径中的反斜杠。

arcname = outpath[len(path_to_dir):].lstrip(os.sep).replace('\\', '_')

-Output Zip
    -folder1_1.txt
    -folder1_2.txt
    -folder2_1.txt
    -folder2_2.txt
