How to change the default encoding in Python?

In Python, the default encoding is the encoding used for strings and other text-based data types unless another encoding is explicitly specified. The default encoding can be changed, but it is not recommended since it can cause compatibility issues with other systems and libraries that assume the default encoding is ASCII or UTF-8.

That being said, if you need to change the default encoding in Python, you can use the sys module to do so. Here’s an example:

import sys

# Set the default encoding to utf-8
sys.setdefaultencoding('utf-8')

Note that in Python 3, the default encoding is already set to UTF-8, so there is no need to change it.
