python str base64

To encode a string to base64 in Python, you can use the base64 module. Here's an example:

import base64

string = "Hello, World!"
encoded_string = base64.b64encode(string.encode("utf-8")).decode("utf-8")

print(encoded_string)

This will output the base64 encoded string:

SGVsbG8sIFdvcmxkIQ==

To decode a base64 string back to its original form, you can use the b64decode method:

decoded_string = base64.b64decode(encoded_string).decode("utf-8")

print(decoded_string)

This will output the decoded string:

Hello, World!
