Converting bytes to int is easily done by int.from_bytes method in python.
Conversion
Big Endian
For using big endian, we can specify "big" to the byteorder argument (the second argument) of int.from_bytes method in Python.
int.from_bytes(b'hello', byteorder='big')
# 448378203247
int.from_bytes(b'\x00\x01', byteorder='big')
# 1
Little Endian
For using little endian, we can specify "little" to the byteorder argument (the second argument) of int.from_bytes method in Python.
int.from_bytes(b'hello', byteorder='little')
# 478560413032
int.from_bytes(b'\x00\x01', byteorder='little')
# 256
