Rename multiple files in Python

Question

How can I rename the following files:

abc_2000.jpg
abc_2001.jpg
abc_2004.jpg
abc_2007.jpg

into the following ones:

year_200         


        

Answer 1

Because I have done something similar today:

#!/usr/bin/env python

import os
import sys
import re

if __name__ == "__main__":
    _, indir = sys.argv

    infiles = [f for f in os.listdir(indir) if os.path.isfile(os.path.join(indir, f))]

    for infile in infiles:
        outfile = re.sub(r'abc', r'year' , infile)
        os.rename(os.path.join(indir, infile), os.path.join(indir, outfile))
