Answer 1

You can use sizeof operator to find it out.
You can either import getsizeof method from the sys module:

from sys import getsizeof
print(getsizeof(20))
#Prints the sizeof the integer 20.

Objects should also have a magicmethod, might be discouraged from using, but works:

print((20).__sizeof__())

Remember that you would sometimes need parentheses, for example 20.__sizeof__() would result in errors, with variables this doesn't cause problems:

a = 20
print(a.__sizeof__())
