Consider the following program. It is supposed to compute the hypotenuse of a right triangle after the user enters the lengths of the other two sides.

a = float(input("Enter the length of the first side:"))
b = float(input("Enter the length of the second side:"))
h = sqrt(a * a + b * b)
print("The length of the hypotenuse is", h)

After adding import math to the code given above, what other change(s) are required in the code to make it fully work ?

Which of the following expressions will result in an error message being displayed when a program containing it is run?

(a) 2.0/4

(b) "3" + "Hello"

(c) 4 % 15

(d) int("5")/float("3")

(e) float("6"/"2")

What is the output produced by following code?

a, b = bool(0), bool(0.0)
c, d = str(0), str(0.0) 
print (len(a), len(b)) 
print (len(c), len(d))

Given a string s = "12345". Can you write an expression that gives sum of all the digits shown inside the string s i.e., the program should be able to produce the result as 15 (1+2+3+4+5).
[Hint. Use indexes and convert to integer]
