mutable and immutable datatypes in python

Question

In python int is immutable so
x=1
x=4
Here we are able to alter x as x is only referencing to the integer object in memory and there are thus two objects (1,4) present in the memory.
Similarly.if a tuple is also immutable then why
x= (1,4)
x[0]=2
will generate an error. Like int datatype tuple should also allow to produce new object keeping the old object still in the memory.
