Jul 5, 2021 · To create byte objects we can use the bytes () function. The bytes () function takes three parameters as input all of which are optional. The object which has to be converted to bytes is passed as the first parameter. Second and third parameters are used only when the first parameter is string. In this case, the second parameter is the encoding ...
Aug 23, 2023 · In Python, the bytes() function is used to create an immutable sequence of bytes. A byte is a unit of data that represents a character or a value in the range of 0 to 255. This function is particularly useful when dealing with binary data or when encoding and decoding text using various character encodings.
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.
Example 1: Return a new bytes object, which is an immutable sequence of integers in the range 0 = x 256. bytes([97, 98, 99]) Example 2: If no argument is given, it returns an empty bytes object. empty_bytes = bytes() Example 3: When a string is passed as an argument, it encodes the string using the specified encoding.
Oct 9, 2019 · 1. Sockets is a good case for using bytes. Also you should use bytes to read/write binary data, like image or audio, from a file or a web API. The str type is an immutable sequence of character, which is typically UTF8 encoded. Obviously if your data is not characters, then doing the UTF8 encoding on it will be inefficient and could cause bugs.
Dec 19, 2023 · As explained previously, bytes is just a data structure in Python. Each data structure is useful in solving a particular kind of problem. The bytes data structure is very useful when we wish to store a collection of bytes in. an ordered manner. a contiguous area of memory. an immutable manner.
