Python 3's bytes and bytearray classes both hold arrays of bytes, where each byte can take on a value between 0 and 255. The primary difference is that a bytes object is immutable, meaning that once created, you cannot modify its elements. By contrast, a bytearray object allows you to modify its elements.
Feb 3, 2016 · There are two questions here, and the answers to them are different. The first question, the title of this post, is What is the proper way to determine if an object is a bytes-like object in Python? This includes a number of built-in types (bytes, bytearray, array.array, memoryview, others?) and possibly
bytes() Syntax. The syntax of bytes() method is: bytes([source[, encoding[, errors]]]) bytes() method returns a bytes object which is an immutable (cannot be modified) sequence of integers in the range 0 <=x < 256. If you want to use the mutable version, use the bytearray() method.
Dec 19, 2023 · Bytes in a Nutshell. The bytes class is a data structure in Python that can be used when we wish to store a collection of bytes in an ordered manner in a contiguous area of memory and we wish for it to remain unchanged. The bytes class comes under binary data types. You can use the bytes() constructor to create a bytes object as shown below
- Decodes bytes using the given encoding

- Truth Value Testing¶ Any object can be tested for truth value, for use in an if or while condition or as operand of the Boolean operations below. By default, an object is considered true unless its class defines either a __bool__() method that returns False or a __len__() method that returns zero, when called with the object.
- Boolean Operations — and, or, not¶ These are the Boolean operations, ordered by ascending priority: Operation. Result. Notes. x or y. if x is true, then x, else y.
- Comparisons¶ There are eight comparison operations in Python. They all have the same priority (which is higher than that of the Boolean operations). Comparisons can be chained arbitrarily; for example, x < y <= z is equivalent to x < y and y <= z, except that y is evaluated only once (but in both cases z is not evaluated at all when x < y is found to be false).
- Numeric Types — int, float, complex¶ There are three distinct numeric types: integers, floating point numbers, and complex numbers. In addition, Booleans are a subtype of integers.
Jun 16, 2023 · Convert String to Bytes. In this example, we will convert Python String to bytes using the bytes() function, for this we take a variable with string and pass it into the bytes() function with UTF-8 parameters. UTF-8 is capable of encoding all 1,112,064 valid character code points in Unicode using one to four one-byte code units.
