OS Module

Import OS Module

First, we need to import the OS Module in our project. So for using the OS Module, we need to add using the “import” statement. Along with that, we are gonna import a time module to make our program wait for some time using the sleep method.

import os
import time

Create a Function for Create Folders

As we know that for creating the function in Python we have to use “def” keyword to define a function.

So let’s create a new function “createFolders(address)” which accepts one argument as the address where we need to create folders.

So for this example let’s create 10 directories or folders using OS built-in Module.

def createFolders(HOME_FOLDER):
    for i in range(10):
            os.mkdir(HOME_FOLDER + str(i) + '-Dir')

Create a Function for Create Files

Since we have declared a function which creates 10 folders at address which we passed as an argument.

Now let’s create a new function for creating files named it as “createFiles(arg)” which accepts one argument as the address where we need to create files.

So for this example let’s create 10 files using OS Module.

def createFiles(HOME_FOLDER):
    for i in range(10):
        f = open(HOME_FOLDER + str(i) + '-File.txt', 'w')
        f.close()

Create a Function for Rename Files

Now we have already defined the function for creating folders and files, so now let’s create a new function for rename the files and folders.

As we already created the folders with “-Dir” at last so now what we want is to replace this “Dir” with Folder.

def renameFiles(HOME_FOLDER):
    os.chdir(HOME_FOLDER)
    for i in os.listdir():
        fileName, fileExt = os.path.splitext(i)
        print(fileName, fileExt)
        os.rename(i, i.replace('Dir', 'Folder'))

Create Main Function Code

Now we have created all the basic functions of the built-in Module. Now what we want is to create a main function to call them to show their functionality.

And also we are gonna use the time module which has sleep(seconds) in this main function to make a pause while creating and renaming files or folders.

if __name__ == '__main__':
    HOME_FOLDER = 'C:/CodezUp/Python/Scripts/Demo/'
    createFolders(HOME_FOLDER)
    createFiles(HOME_FOLDER)
    time.sleep(10)
    renameFiles(HOME_FOLDER)

Output

Source Code :

import os
import time

def createFolders(HOME_FOLDER):
    for i in range(10):
            os.mkdir(HOME_FOLDER + str(i) + '-Dir')

def createFiles(HOME_FOLDER):
    for i in range(10):
        f = open(HOME_FOLDER + str(i) + '-File.txt', 'w')
        f.close()

def renameFiles(HOME_FOLDER):
    os.chdir(HOME_FOLDER)
    for i in os.listdir():
        fileName, fileExt = os.path.splitext(i)
        print(fileName, fileExt)
        os.rename(i, i.replace('Dir', 'Folder'))

if __name__ == '__main__':
    HOME_FOLDER = 'C:/CodezUp/Python/Scripts/Demo/'
    createFolders(HOME_FOLDER)
    createFiles(HOME_FOLDER)
    time.sleep(10)
    renameFiles(HOME_FOLDER)
