The byteorder argument determines the byte order used to represent the integer. Python. The Python hex () function is used to convert decimal to hexadecimal integers, as a string. If byteorder is “little”, the most significant byte is at the end of the byte array. It returns 0 when the function receives no argument. Also, we will append the converted item to a new list. The method is invoked on an int value, is not supported by Python 2 (requires minimum Python3) for execution.
