Answer 3

    import os
import re
from pathlib import Path

for f in os.listdir(training_data_dir2):
  for file in os.listdir( training_data_dir2 + '/' + f):
    oldfile= Path(training_data_dir2 + '/' + f + '/' + file)
    newfile = Path(training_data_dir2 + '/' + f + '/' + file[49:])
    p=oldfile
    p.rename(newfile)

Answer 4

File may be inside a directory, in that case specify the path:

import os
old_file = os.path.join("directory", "a.txt")
new_file = os.path.join("directory", "b.kml")
os.rename(old_file, new_file)

Answer 5

Use os.rename. But you have to pass full path of both files to the function. If I have a file a.txt on my desktop so I will do and also I have to give full of renamed file too.

 os.rename('C:\\Users\\Desktop\\a.txt', 'C:\\Users\\Desktop\\b.kml')

Answer 6

import shutil
import os

files = os.listdir("./pics/") 

for key in range(0, len(files)):
 print files[key]
 shutil.move("./pics/" + files[key],"./pics/img" + str(key) + ".jpeg")

this should do it. python 3+
