- What is the result of the following expression in Python: 5 is 5.0?

B) False
C) None

Solution

The answer is A) True. The expression "a" not in ["b", "c", "d"] checks if the string "a" is not present in the list ["b", "c", "d"]. Since "a" is not in the list, the expression returns True.

The correct identity operator in Python to check if two objects are the same object is C) is. The 'is' operator checks if both the variables point to the same object whereas the '==' operator checks if the values for the two variables are the same.
-
The answer is B) False. In Python, the 'is' operator checks for object identity. While 5 and 5.0 are equal in value, they are not the same object. Therefore, the expression 5 is 5.0 returns False.
