Question

Differentiate between 'w' and 'a' file modes in Python.

Answer 1

Here are the differences between 'w' and 'a' modes:

1. 'w' or write mode. This opens the file for writing. If the file already exists, its contents are erased.
2. 'a' mode or add mode. It opens the file to add extra data at the end while keeping previous information.
