This article aims at demonstration and working of an interconversion of different data types to bytes (), usually useful for encoding schemes.
I’ll cover working with the struct package, the bytearray built-in and the ctypes module.Be careful with slicing a python bytearray, bytes or array.array. int:n n bits as a signed integer.
A concrete object belonging to any of these categories is called a file object.Other common terms are stream and file-like object. This article aims at demonstration and working of an interconversion of different data types to bytes(), usually useful for encoding schemes.Bytes accept string as argument and requires an encoding scheme with it to perform it.
