Answer 1

When a single integer is specified in parentheses, it is taken as an integer.
So, (5) is same as 5.

Just as we do in math:
7*5 is same as 7*(5)

But, when you put a comma after 5, you get a tuple with a single integer element.

Just try finding out type of (5,)

Answer 2

A single element in parentheses which is int or float or boolean is considered as its original value . A single element in a parentheses can't make a tuple .
