bytes() function is used to find the new bytes object in Python which is an immutable (cannot be modified) sequence of integers in the range, 0 <=x < 256. For using muteable version use bytearray() function.
bytes() function is a part of Python Built-in Functions.
Syntax of bytes() Function
The syntax of bytes() function in Python is:
1 | bytes([source[, encoding[, errors]]]) |
Parameters of bytes() Function in Python
source – Where source is the initialization of bytes array. This could be a string, integer, object, iterable and an array of size 0. This parameter is optional.encoding – Where encoding is the encoding of the string. This parameter is also optional.errors – Where errors are actions that needed to take when encoding fails. This parameter is also optional.
Compatibility
bytes() function is only available and compatible with Python 3.x.
Return Value of bytes() Function in Python
bytes() function returns a new immutable “bytes” object initialized with the given size and data.
Python bytes() Function Example 1
1 2 3 4 5 | stringValue = "This is my Test String." # string value passed to bytes with utf-8 encoding parameter myArray = bytes(stringValue, 'utf-8') print(myArray) |
Output:
b'This is my Test String.'
Python bytes() Function Example 2
1 2 3 4 | integerValue = 7 myArray = bytes(integerValue) print(myArray) |
Output:
b'\x00\x00\x00\x00\x00\x00\x00'Python bytes() Function Example 3
1 2 3 4 | elementList = [5,6,7,8] myArray = bytes(elementList) print(myArray) |
Output:
b'\x05\x06\x07\x08'
