Os.rename 文件覆盖

Question

I am making a Python project that renames multiple files. However, sometimes the files overwrite.

suffixes = ['.pdf', '.epub', '.mobi']
file_list = []


def change_fname(dir_name, part=' (z-lib.org)', action='remove'):
    fnames = os.listdir(dir_name)
    for suffix in suffixes:
        fnames_suffix = [f for f in fnames if f.endswith(suffix)]
        for fname in fnames_suffix:
            print(f'{action} "{part}" into/from "{fname}"')
            if action == 'remove' and fname.endswith(part+suffix):
                new_name = fname[:-len(suffix) - len(part)] + suffix
                print(f'fname is {fname}')
            elif action == 'insert':
                new_name = fname[:-len(suffix)] + part + suffix
            else:
                raise Exception(f'Unknown Action: {action}')
            print(new_name)
            old_file = os.path.join(dir_name, fname)
            new_file = os.path.join(dir_name, new_name)
            os.rename(old_file, new_file)


file_to_show = '/Users/ChrisHart/Downloads/test i love you daddy/'
subprocess.call(["open", "-R", file_to_show])

if __name__ == '__main__':
    dir_name = '/Users/ChrisHart/Downloads/test i love you daddy/'
    try:
        change_fname(dir_name, part=' (z-lib.org)', action='remove')
    except Exception as ex:
        print(ex)

This is my program ^

file (part).pdf
file.pdf

The file will delete " (part)", so we get this

file.pdf
file.pdf

And they overwrite.

file.pdf

How can I fix this overwriting?

I also wrote a script that changes multiple files. Maybe my code helps you understand your problem:

import os

print(os.getcwd())           #Gives you your current directory

os.chdir('/PATH/TO/FILES')   #Change directory to the files


for i in os.listdir('/PATH/TO/FILES'):
    os.rename(i, i.replace('(z-lib.org)', ' '))  #replaces z-lib with one whitespace
    
print(i)  

I know what you're trying to replace :D ... I did the same thing
