python convert hex string to bytes

Title: Python Tutorial: Converting Hex String to Bytes
Introduction:
In Python, working with hexadecimal data is common, especially when dealing with binary data or low-level operations. Converting a hex string to bytes is a straightforward process, and in this tutorial, we'll explore the steps to achieve this with practical code examples.
Python provides a built-in method called fromhex() that allows you to convert a hexadecimal string to bytes. Let's start by importing this method:
Step 2: Use fromhex() to convert hex string to bytes
Now that we have imported the necessary method, let's use it to convert a hex string to bytes. The fromhex() method takes a hexadecimal string as input and returns a bytes object.
In this example, replace the hex_string variable with your own hexadecimal string. The bytes_data variable will store the converted bytes.
Step 3: Handling spaces in the hex string
The fromhex() method automatically handles spaces in the hexadecimal string. This is useful when dealing with formatted hex strings. Let's look at an example:
Step 4: Error handling for invalid hex strings
It's important to handle cases where the input hex string is not valid. The fromhex() method can raise a ValueError if the input contains non-hexadecimal characters. Use a try-except block to handle such cases:
