Rename multiple files using Python

To rename files in Python, use the rename() method of the os module. The parameters of the rename() method are the source_address (old name) and the destination_address (new name).

Install and Import the OS module

To install the OS module −

pip install os

To import −

import os

Rename multiple files using rename() method

The rename() method can be easily used to rename multiple files −

Example

import os
# Function to rename multiple files
def main():
	i = 0
	path="E:/amit/"
	for filename in os.listdir(path):
		my_dest ="new" + str(i) + ".jpg"
		my_source =path + filename
		my_dest =path + my_dest
		# rename() function will
		# rename all the files
		os.rename(my_source, my_dest)
		i += 1
# Driver Code
if __name__ == '__main__':
	# Calling main() function
	main()

The above will rename all the files in a folder “amit”.

Rename specific multiple files

In Python, you can select which multiple files in a folder are to be renamed.

import os

filesRename = ['demo_1.txt', 'demo_2.txt', 'demo_3.txt',]
folder = r"E:\docs"

# Iterate
for file in os.listdir(folder):
	# Checking if the file is present in the list
	if file in filesRename:
		oldName = os.path.join(folder, file)
		n = os.path.splitext(file)[0]

		b = n + '_new' + '.txt'
		newName = os.path.join(folder, b)

		# Rename the file
		os.rename(oldName, newName)

res = os.listdir(folder)
print(res)

The above will rename only 3 files in the docs folder.
