Rename All Files in a Directory with consecutive numbers in Python

Question

I would like to rename all file (the filenames have no clear pattern) into filenames with consecutive numbers eg:

Files in Directory:

agh_uio78.jpg hhaq23klp.png mickey.tiff

into

001.jpg 002.png 003.tiff

This will give me a result with no extension:

import os

FList = os.listdir(os.getcwd())
FListC = FList[1:]

m = 0
for i in FListC:
    os.rename(i,str(m))
    m = m+1

Result:

1 2 3

Answer 1

import os

FList = os.listdir(os.getcwd())
FListC = FList[1:]

m = 0
for i in FListC:
    fileExtension = os.path.splitext(i)[1]
    os.rename(i,str(m)+fileExtension)
    m = m+1

You forgot to save the extension of the file.
Above code will grab the file's extension and concatenate to your incremented file name
