Python B

Python B. Python bytes() Function The python bytes() function in Python is used for returning a bytes object It is an immutable version of bytearray() function It can create empty bytes object of the specified size Signature bytes(source) bytes(encoding) bytes(error) Parameters source is used to initialize the bytes object It is an optional parameter.

Bytes and bytearray objects contain single bytes – the former is immutable while the latter is a mutable sequence 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.

Python Data Types Overview Here is a brief overview of all builtin Python data types (meaning they are implemented for you in Python and you can use them via a class without importing additional modules) and some additional data types (eg date and time which are not builtin and require importing a module).
