Why does a variable and the value it points to both have the same address in Python 3.6.5?

Question

Why are these the same address? Is it because the integer 4 is actually an Object in Python and therefore a variable which points to this same integer will have the memory address of this particular integer Object?

hex(id(4)) #will return '0x10b684900' 

x = 4

hex(id(x)) #will return '0x10b684900'

The python interpreter doesn't need tho save the value 4 multiple times because int is immutable. So all variables with the value four point to the same memory location.
