Why f=(0) is considered integer instead of tuple

Question

While executing the code
f=(0)
print type(f)
It returns integer as type

Answer 1

I guess because python thinks parentheses around 0 are for calculations or operators.

But there's one think I'm sure about: You should use "," if you want python to recognize it as a tuple:
f=(0,)

Answer 2

if you do:

f = (0,1)

the result will be tuple. The same happens if you do:

f =() #or
f = (0,)

Answer 3
