Nope. It will bind the name 'a' to the integer object. > Changing 'a' will not > change the value at lst[42]["pos"] Integers are immutable - they can't be modified. So, "Changing 'a'" means binding the name 'a' to a different object. This will have no effect on other references to the original object.
