How to create a fixed size (unsigned) integer in python?

Question

I want to create a fixed size integer in python, for example 4 bytes. Coming from a C background, I expected that all the primitive types will occupy a constant space in mem

Answer 1

you are missing something here I think

when you send a character you will be sending 1 byte so even though

sys.getsizeof('\x05') 

reports larger than 8 you are still only sending a single byte when you send it. the extra overhead is python methods that are attached to EVERYTHING in python, those do not get transmitted

you complained about getsizeof for the struct pack answer but accepted the c_ushort answer so I figured I would show you this

>>> sys.getsizeof(struct.pack("I",15))
28
>>> sys.getsizeof(c_ushort(15))
80

however that said both of the answers should do exactly what you want
