What are some useful functions in the Python os module?

The os module in Python provides a way to use operating system-dependent functionality. Some useful functions include:

1. os.listdir(path): Lists all files and directories in the specified path.
2. os.getcwd(): Returns the current working directory.
3. os.mkdir(path): Creates a new directory at the specified path.
4. os.remove(path): Deletes a file at the specified path.
5. os.path.join(path, *paths): Joins one or more path components intelligently.

Can you explain how to use os.getcwd()?

Sure! The os.getcwd() function returns the current working directory as a string. You can use it like this:

import os
current_directory = os.getcwd()
print('Current Directory:', current_directory)

This will print the path of the directory where your script is running.

What about creating a directory with os.mkdir()?

To create a directory using os.mkdir(), you can specify the path where you want the new directory to be created. Here's an example:

import os
os.mkdir('new_directory')

This will create a directory named 'new_directory' in the current working directory.

Are there any functions for file manipulation?

Yes, the os module has several functions for file manipulation, such as:

• os.remove(path): Deletes a file.
• os.rename(src, dst): Renames a file or directory from src to dst.
• os.path.exists(path): Checks if a file or directory exists at the specified path.
