Renaming All Files in a Folder With Python
Hello Guys,
In this Python Tutorial, We are going to learn how to Rename Files with Python.
Actually there is no problem if we are renaming one or two files, but when we want to rename many files in bulk then the problem begins. It is not easy to rename many files.
Then We came with a Solution. With the help of Python, we can rename as many files as we want all at once in One Click.
There are many types in Renaming a file. In some cases, you want to add Prefix, in some you want to add Sufix. In Some Cases, you want to remove either Prefix or Sufix.
So lets start with first case Adding a Prefix to files
With No Delay Let’s Get Started.
First Create Python File Somewhere in your Laptop.
Now Open the Python file in Editor Mode. Start writing this code.
So There are many text files with names of your friends in a folder and you decided to add a prefix “Friend” separating with “_” for the name of each file as shown in the image below.
So Let’s see how the code goes.
import os
os.chdir("C:\\Users\\Ramesh Naidu\\Desktop\\Code World\\Python Tutorials\\Rename Files")
for f in os.listdir():
f_name, f_ext = os.path.splitext(f)
frnd = ['Friend']
frnd_n = f_name.join(frnd)
print('{}_{}{}'.format(frnd_n, f_name, f_ext))
new_name = '{}_{}{}'.format(frnd_n, f_name, f_ext)
os.rename(f, new_name)
After Running this Code the Output is
So Here is the Output of renaming all files at Once in One Click.
Note: Change os.chdir path to your own.
That’s it Now you can Rename multiple files by adding Prefix all at Once.
In the Next Tutorial we’ll see about Renaming all Files by adding Sufix
