In the first case, 2 == True, you are comparing the integer value 2 against the boolean value True. You are essentially asking whether those two are the same. In Python those are not the same, and so the python interpreter returns False.

In the second case, bool(2), you cast the integer to a boolean. You are basically asking, if this was a boolean, what boolean value would it be? In Python, the bool method will always return True, unless:

  • the provided object is empty, like [], {}, ()
  • the provided object is False, like 3 == 4
  • the provided object is 0
  • the provided object is None

Since the integer value 2 is none of the above, bool(2) will return True.

Hope this helps!
