How do I encode a string in Base64 using Python?

You can use the base64 module in Python. Here's a simple example:

import base64

# String to encode
string_to_encode = 'Hello, World!'

# Encoding the string
encoded_bytes = base64.b64encode(string_to_encode.encode('utf-8'))
encoded_string = encoded_bytes.decode('utf-8')

print(encoded_string)  # Outputs: SGVsbG8sIFdvcmxkIQ==

What if I want to decode a Base64 string back to its original form?

You can decode a Base64 string using the same base64 module. Here's how:

import base64

# Base64 string to decode
base64_string = 'SGVsbG8sIFdvcmxkIQ=='

# Decoding the string
decoded_bytes = base64.b64decode(base64_string)
decoded_string = decoded_bytes.decode('utf-8')

print(decoded_string)  # Outputs: Hello, World!

Are there any other encoding options available in Python?

Yes, Python supports various encoding formats like UTF-8, ASCII, and more. You can use the codecs module for additional encodings.

Can you give me an example of using UTF-8 encoding?

Sure! Here's how you can encode and decode a string using UTF-8:

# String to encode
string_to_encode = 'Hello, World!'

# Encoding the string
encoded_string = string_to_encode.encode('utf-8')

# Decoding the string
decoded_string = encoded_string.decode('utf-8')

print(decoded_string)  # Outputs: Hello, World!
