“How To Create Python Bytes Object From Long Hex String?” ~ bbaz
Introduction
If you’re a Python programmer, you’re probably familiar with the bytes data type. This data type is used to represent binary data in Python, and it’s often used to represent data in network protocols, file formats, and other applications that deal with binary data. One of the challenges of working with binary data is converting between different representations of the data. In this article, we’ll be focusing on one specific conversion: how to convert a long hex string to a Python bytes object.
The Challenge
Let’s start by considering what makes converting a long hex string to a bytes object difficult. There are a few factors that contribute to the challenge:
Length
A long hex string can be quite long – potentially thousands or even millions of characters. This means that any conversion function needs to be efficient and not have a significant performance impact.
Binary Nature
The nature of the data being represented – binary data – means that we need to ensure that the bits in the resulting bytes object are accurate and consistent with the original string representation. Any errors in the conversion could result in serious issues in code that relies on the binary data being represented accurately.
Python 2 vs Python 3
Finally, it’s worth mentioning that there are some differences between Python 2 and Python 3 that make this conversion trickier. Python 2 and Python 3 use different default string types, so a conversion function that works in Python 3 may not work as expected in Python 2 (and vice versa).
A Solution
So, how can we convert a long hex string to a Python bytes object quickly and accurately? There are a few different methods out there, but one particularly promising method is to use the built-in Python library function binascii.unhexlify().
Using binascii.unhexlify()
The binascii.unhexlify() function is a simple and efficient way to convert a hex string to a bytes object. Here’s how you can use it:
| Python code | Description |
|---|---|
import binascii |
Import the binascii library |
hex_string = '546869732069732061207465737420737472696e67' |
Define your hex string (in this case, ‘This is a test string’) |
bytes_object = binascii.unhexlify(hex_string) |
Use unhexlify() to convert the hex string to a bytes object |
And that’s it! You now have a bytes object that accurately represents the original hex string.
Example Use Case
Let’s look at an example use case for this conversion method. Imagine you’re working on a project that involves decoding messages sent between two devices over a network. Each message is in hex format, and you need to convert them to bytes objects to perform some processing.
Here’s some code that demonstrates how you could use binascii.unhexlify() to convert a hex string to a bytes object in this scenario:
| Python code | Description |
|---|---|
import binascii |
Import the binascii library |
hex_string = '546869732069732061207465737420737472696e67' |
Define your hex string (in this case, ‘This is a test string’) |
message_hex = receive_message() |
Receive the next message in hex format |
message_bytes = binascii.unhexlify(message_hex) |
Convert the message to a bytes object |
process_message(message_bytes) |
Process the message as a bytes object |
This example illustrates how you can use binascii.unhexlify() to easily convert a long hex string to a bytes object, even in the context of a larger program.
Conclusion
Converting a long hex string to a Python bytes object can be a tricky task, but using the built-in binascii.unhexlify() function can make the process much easier. This function is efficient, accurate, and easy to use, making it an ideal tool for anyone dealing with binary data in Python.
Overall, we highly recommend using binascii.unhexlify() for converting long hex strings to bytes objects. It’s a reliable and efficient method that will help ensure your code is handling binary data accurately and effectively.

When it comes to working with Python, you may need to convert a long hex string to a Python bytes object. This process can be tricky if you are not familiar with the necessary steps. Here are some of the most common questions people ask about converting long hex strings to Python bytes objects and their respective answers:
-
What is a long hex string?
A long hex string is a sequence of hexadecimal characters that represents a large number or a binary data set. It is often used in cryptography, networking, and other applications that require the transfer or storage of binary data.
-
Why do I need to convert a long hex string to a Python bytes object?
Python bytes objects are a way to represent binary data in Python. They are used for many purposes, such as sending and receiving data over a network or storing binary data in a file. Converting a long hex string to a Python bytes object allows you to work with the data more easily in a Python program.
-
How can I convert a long hex string to a Python bytes object?
To convert a long hex string to a Python bytes object, you can use the built-in function
bytes.fromhex(). This function takes a hex string as input and returns a bytes object. Here is an example:hex_string = 48656c6c6f20576f726c64bytes_object = bytes.fromhex(hex_string)print(bytes_object)This code will output:
b'Hello World' -
What if my hex string is too long to fit on one line of code?
If your hex string is too long to fit on one line of code, you can split it into multiple lines using the backslash (\) character. Here is an example:
hex_string = 48656c6c6f20576f726c64\20746f20546865204265616d73bytes_object = bytes.fromhex(hex_string)print(bytes_object)This code will output:
b'Hello World to The Beams'
