In this tutorial, you will learn various ways to write text files in Python.

Below is the basic syntax of the open() function:

f = open(file, mode, encoding='utf-8')

You can create a new file or append to existing file content or overwrite the existing content of a file using python with the open method with the appropriate access modifier.

The following are the 3 different modes.

“a” – Append – will append to the end of the file
“w” – Write – will overwrite any existing content
“x” – Create – will create a file, returns an error if the file exists

Append to the existing file.

To append something to a file, use the code snippet as follows:

with open('file.txt', 'a') as f:
 f.write("Something\n")

Overwrite the existing file.

To write something to a file and overwrite it:

with open('file.txt', 'w') as f:
 f.write("Something\n")

Create a new file and write.

To create a new file and throw an error if the file exists

with open('file.txt', 'w') as f:
f.write("Something\n")
