ctypes in python size with the `sys.getsizeof(Var)` method vs `ctypes.sizeof(Var)`

Question

I have a question about variable size in python, I\'m using the the Ctypes because i want a 1 byte number, but when I tried to check it\'s size in python (via sys.gets

Answer 1

The ctypes module is used for creating and manipulating C data types in Python. That is why ctypes.sizeof(ctypes.c_byte(1)) returns 1.

>>> import sys
>>> help(sys.getsizeof) Help on built-in function getsizeof in module sys:

getsizeof(...)
    getsizeof(object, default) -> int

    Return the size of object in bytes.

while

>>> import ctypes
>>> help(ctypes.sizeof)
Help on built-in function sizeof in module _ctypes:

sizeof(...)
    sizeof(C type) -> integer
    sizeof(C instance) -> integer
    Return the size in bytes of a C instance
