In the python language online, file handling is done using the built-in open() function. It allows you to read, write, or modify files easily and efficiently.

Using the built-in open() function.
Example:

 
with open("data.txt", "r") as f:
content = f.read()
 
with open("data.txt", "w") as f:
f.write("Hello!")
 

This method ensures that files are properly opened and closed using context managers, making your code cleaner and more secure.
