Python bytes() method - GeeksforGeeks

July 11, 2025 - By passing a single integer to bytes(), Python will create a bytes object of that length, filled with zero values (because a byte is initially 0).

For performance reasons, the value of errors is not checked for validity unless an encoding error actually occurs, Python Development Mode is enabled or a debug build is used. For example: >>> encoded_str_to_bytes = 'Python'.encode() >>> type(encoded_str_to_bytes) <class 'bytes'> >>> encoded_str_to_bytes b'Python'

Python Bytes: Syntax, Usage, and Examples

For instance, compression libraries often accept or return byte arrays. Python bytes provide a fast and reliable way to handle binary data. You can convert between strings and bytes easily using .encode() and .decode(). When you need mutability, use bytearray.

Bytes objects can be constructed the constructor, bytes(), and from literals; use a b prefix with normal string syntax: b'python'. To construct byte arrays, use the bytearray() function.

July 30, 2021 - Python bytes() function is used to convert an object to an immutable (cannot be modified) byte object of the given size and data.

Bytes Objects: Handling Binary Data in Python – Real Python

March 5, 2025 - The difference between bytes and bytearray is that bytes objects are read-only, while bytearray objects are mutable. You convert a Python string to bytes using the str.encode() method, the bytes() function, or the codecs module.

r/learnpython on Reddit: I don't understand Python bytes objects, its purpose and when to use it?

June 11, 2020 -

I am haveing some hard time here trying to understand Python's bytes object. Why it was intruduced, when to use it? and Why to use it? Why older python didn't have bytes object, and things were kind ok, and they came up with the ideas to invent bytes object?

Appraciate if someone could point to an artice/video where bytes object is explaned like if I am five years old.

Thanks.

bytes objects are used whenever you need to deal with some sort of data you don't necessarily understand. For example, let's say you're opening a network connection. What do you send over that connection? You send data in some form, and that data doesn't have to be text - it could be, but it could also be a more complicated protocol with its own data format like, say, HTTP/2 or SSH. How do you represent that data in Python? You can't use str, because the data might not be text, or even representable as text. You could use a list of numbers, but that's really inefficent. Thus, bytes.

A chunk of bytes is just raw memory or storage contents - zeroes and ones collected into groups of eight bits, and it doesn't have any specific meaning until you decide how to interpret it. If I have four bytes, what do they mean? Are they ASCII characters, UNICODE codepoints, or an integer? If they're an integer, are they big-endian or little-endian? What if your program doesn't need to know - if it's just shifting the bytes from one place to another, it doesn't matter. Networks and files are of this nature - the data could be anything, so if you don't have to know what's in there, it's not worth checking. The operating system thus usually makes no assumptions as to the type of data held within the bytes when transporting it over the network or to and from storage. I'm afraid this explanation has got pretty long, but I've tried to cover enough background to explain the main concepts and drivers behind why we now have the bytes type. The TL;DR is "we have the bytes type because it was necessary to get around problems caused by assumptions in code that would cause difficult-to-debug problems when those assumptions were not met; treating data of an unknown encoding as raw bytes gives you explicit errors that force you to deal with the unknowns rather than just hoping for the best". So, if some chunk of bytes is supposed to be text, you need to know how it's encoded - is it ASCII, UNICODE or EBCDIC? If you guess and treat it as ASCII when it's EBCDIC, you will get gibberish, and vice-versa. Old Python, and lots of other languages of the time treated raw data as strings, and this ended up causing a lot of problems in corner cases, especially to do with networking and file I/O. Lots of libraries accepted strings as input, and assumed that they contained ASCII data, or other textual encodings, and failed in unexpected ways when that assumption was incorrect. Then, as the internet became ubiquitous around the world, extended character encodings became important. Standard ASCII, the encoding used at the time, represents each character with a 7-bit byte, so it only has 127 code points, though you can go up to 255 if you use extended 8-bit versions, so it doesn't have an easy way to display all the characters and punctuation common in non-English speaking languages. In the early 90's, you used to select whichever codepage was best for your language, but in doing so, you often couldn't display characters from other languages, which was bad if you wanted to work internationally. Imagine if Facebook only worked with the standard American symbol set - no accents, no other currency symbols, no Chinese, or other non-alphabetical texts... it wouldn't have ever got popular outside of the US. So Unicode became a thing, which seeks to encode all character sets eventually. It's based on ASCII, but adds the ability to represent character points which are composed of more than one byte, thus, if you try to print out Unicode as ASCII, you will end up printing garbage whenever you hit a "long character". To complicate things further, there are multiple ways of storing Unicode - variable length, fixed-length in various sizes. You really need to know what you're dealing with to process it properly. In the end, a decision was made to transition Python over to support Unicode properly, and in order to prevent functions that accepted a string, and expected it to have a specific encoding choking on data that didn't match that expectation, a new raw data concept - bytes - was introduced. Now if you try to feed binary data into a function that expects a string, it will cause an error, rather than subtly screwing up because the data doesn't match its expectations.
