For (at least) Python 3.7. According to the docs: bytes objects are immutable sequences of single bytes. bytearray objects are a mutable counterpart to bytes objects. And that's pretty much it as far as bytes vs bytearray. In fact, they're fairly interchangeable and designed to flexible enough to be mixed in operations without throwing errors.
Jul 14, 2020 · 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.
Nov 28, 2023 · In Python 2, both str and bytes are the same typeByte objects whereas in Python 3 Byte objects, defined in Python 3 are “ sequence of bytes ” and similar to “ unicode ” objects from Python 2. In this article, we will see the difference between byte objects and strings in Python and also will look at how we can convert byte string to normal string and vice versa.
- 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.
May 25, 2023 · A bytes object is an immutable sequence of bytes, conceptually similar to a string. Because each byte must fit into 8 bits, each member x {\displaystyle x} of a bytes object is an unsigned int that satisfies 0 ≤ x ≤ 0 b 1111 _ 1111. {\displaystyle 0\leq x\leq 0b1111\_1111.} The bytes object is important because data written to disk is ...
Jan 25, 2024 · Python 3 differentiates between bytes and strings. Metaclass Definition: Python 2 uses the __metaclass__ attribute, while Python 3 uses the metaclass keyword in class definition. Built-in range() Function: Python 2’s range() generates a list, while Python 3’s range() returns a range object. Performance: Python 2 is generally considered ...

Feb 15, 2006 · This PEP outlines the introduction of a raw bytes sequence type. Adding the bytes type is one step in the transition to Unicode-based str objects which will be introduced in Python 3.0. The PEP describes how the bytes type should work in Python 2.6, as well as how it should work in Python 3.0. (Occasionally there are differences because in ...
