Why is this Isinstance function not working?

Question

This does not print anything for some reason.

---

main = 60

x = isinstance(main, int)

if x == ("True"):  
   print("True") 

elif x == ("False"):  
   print("False")

Answer 1

The boolean value which is returned by the isinstance() function is not a string, but (as you may been able to guess) a boolean.

To rewrite the code provided:

main = 60
x = isinstance(main, int)
if x is True:
    print("True")
elif x is False:
    print("False")

However, since booleans can be conditions themselves, and isinstance() returns a boolean, I would recommend this approach:

main = 60
if isinstance(main, int):
    print("True")
else:
    print("False")

Alternatively, even simpler:

main = 60
print(isinstance(main, int))
