Python rename files that begins with matching string

Do you want to rename a number of files that begins with a specific name or string? I wrote this small Python script that does that. Of course, you can also do this with Bash or Powershell. I hope somebody might find it useful.

import os
import sys
from os import path

parameters = sys.argv[1:]
if len(parameters) == 0:
    print(f"usage: {sys.argv[0]} <startswith-string>")
    sys.exit(0)

if len(parameters) > 0:
    for file in os.listdir():
        if file.startswith(parameters[0]) and path.isfile(file):
            old_name = file
            new_name = file[len(parameters[0]):]
            print(f"Renaming {old_name} -> {new_name}")
            os.renames(old_name, new_name)
