Following expression does not report an error even if it has a sub-expression with 'divide by zero' problem:

3 or 10/0

What changes can you make to above expression so that Python reports this error?

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))

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 ?

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)

When this program is run, the following output is generated (note that input entered by the user is shown in bold):

Enter the length of the first side: 3
Enter the length of the second side: 4
Traceback (most recent call last):
h = sqrt(a * a + b * b)
NameError: name 'sqrt' is not defined

Why is this error occurring? How would you resolve it ?
