Python base64 Module
Example
Encode and decode a string using Base64:
import base64
s = "Linus".encode()
b = base64.b64encode(s)
print(b)
print(base64.b64decode(b).decode())

Definition and Usage
The base64 module encodes binary data into ASCII strings using Base16, Base32, Base64, and related encodings.
Use it to transfer binary data in text-based formats, handle URLs safely, or embed small assets in text documents.
