As per my knowledge python interpreter creates references from 0 to 256 for int objects,at the start itself. Here I got output 3,[44,2,3], for the list I understood, but why the same thing did not happen with int object.I expect output as 1,[44,2,3].Can anyone explain to me why this behavior?. I use python 3.

    def change(var, lst):
        var = 1
        lst[0] = 44
    k = 3
    a = [1, 2, 3]
    change(k, a)
    print(k)
    print(a)
 
output got:3 [44,2,3]
expected output: 1,[44,2,3]
