Answer 1

import os

# Set the path
path = 'a\\b\\c'  
# save current working directory
saved_cwd = os.getcwd()
# change your cwd to the directory which contains files
os.chdir(path)
os.rename('a.txt', 'b.klm')
# moving back to the directory you were in 
os.chdir(saved_cwd)

Answer 2

You can use os.system to invoke terminal to accomplish the task:

os.system('mv oldfile newfile')

Answer 3

os.rename(old, new)

This is found in the Python docs: http://docs.python.org/library/os.html

Answer 4

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+

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

Using the Pathlib library's Path.rename instead of os.rename:

import pathlib

original_path = pathlib.Path('a.txt')
new_path = original_path.rename('b.kml')
