In python all numbers are immutable. This means there is one object ( a
region in the memory ) created every time we do an numeric operation. I
hope there should have been some good reasons why it was designed this way.
But why not have mutable numbers also in the language

You can use the built-in function "eval" to return how Python evaluates

In other words, eval will take your string that looks like a tuple, and
return an actual tuple object.
Note that the 'u' prefix in your string will cause an
