Python解压并将“_”添加到新提取的文件中

Question

With this code, I extract the files from the zip file, but if there is a file with the same name as the files I extracted in a different zip file, it overwrites this file. I want this file to be extracted by adding the "_1" to the end. Can you help me with this?

import zipfile, os, shutil
myZip = zipfile.ZipFile('abc.zip')    

directory_to_extract_to = "place of extraction path"

for file in myZip.filelist:
    if file.filename.endswith('.txt'):
        source = myZip.open(file)
        target = open(os.path.join(directory_to_extract_to, os.path.basename(file.filename)), "wb")

        with source, target:
            shutil.copyfileobj(source, target)

eg; okay.txt >>> extract new file with the same name >>> okay_1.txt >>> okay_2.txt

I believe this will answer your question:

import zipfile, os, shutil

myZip = zipfile.ZipFile('abc.zip') 

directory_to_extract_to = "place of extraction path"

for i,file in enumerate(myZip.filelist):
    if file.filename.endswith('.txt'):
        if file.filename not in os.listdir(directory_to_extract_to):
            path=os.path.join(directory_to_extract_to, os.path.basename(file.filename))
        else:
            path=os.path.join(directory_to_extract_to, os.path.basename(file.filename.replace(".txt",str(i)+".txt")))
        source = myZip.open(file)
        target = open(path, "wb")

        with source, target:
            shutil.copyfileobj(source, target)

What we are doing here is, searching file name in that extracting directory if found then add iteration number in file name otherwise same as what you are doing. We are using iteration number so, you may not get the continuous number in file name but I believe, it solves your issue.
