Question
What does this code do: isinstance(bool == bool,bool)?What is the output and why?2.2 What does this code do: a = 3 == 3? What is the result andwhy?

Solution
-
isinstance(bool == bool,bool)checks if the result ofbool == boolis an instance ofboolclass. The output isTruebecausebool == boolisTrueandTrueis an instance ofboolclass. -
a = 3 == 3assigns the result of3 == 3to variablea. The result isTruebecause3is equal to3. The difference betweena = 3 == 3anda == 3 = 3is that the latter is a syntax error. In Python, you can't chain assignment and equality checks like that. -
Here are three lines of code that fulfill your request:
x = 37
y = 4
print(x * y)
This code first assigns 37 to x, then assigns 4 to y, and finally prints the result of x * y which is 148.
