How to Fix \'TypeError: \'str\' does not support the buffer interface\' in Python 3\'s gzip.open()?

TypeError: 'str' does not Support the Buffer Interface

When attempting to utilize the gzip.open() function with Python 3, an error may arise: "TypeError: 'str' does not support the buffer interface." This error stems from the difference between string handling in Python 3 and its predecessors.

In Python 3, string objects are not directly compatible with the buffer interface, making it necessary to convert them to bytes before writing them to a compressed file. This can be accomplished by encoding the string with an appropriate encoding, such as UTF-8:

plaintext = input("Please enter the text you want to compress").encode("utf-8")
filename = input("Please enter the desired filename")
with gzip.open(filename + ".gz", "wb") as outfile:
    outfile.write(plaintext)

Additionally, it is recommended to avoid using keywords such as "string" and "file" as variable names, as they conflict with built-in modules and functions.
