Why this Strange behaviour with tupples

Question

Look at the code and tell me if you don't think that python acts strangely with these tuples of tuples https://code.sololearn.com/cKhnrli86Tah/?ref=app

Answer 1

x = (2) #int
x = 2
x = (2,) #tuple
x = 2,
#You should add a comma if you want a tuple with one value

Answer 2

On line 1 you have:
F=((2,))

That is not a nested tuple, i.e. tuple(tuple with one element), it's just a (tuple with one element) wrapped in a discarded set of grouping parentheses.

Without a comma, Python can't tell the difference between parenthesis used for order of operations and a tuple with one element ... and neither can people.

That's why 1-element tuples show/require a trailing comma, and 2+ elements do not:

F=((2,),)

That's a tuple(tuple with one element)
