SUGGESTED LAB. EXERCISES
1. Write a program to check the divisibility of a number by 7 that is passed as a parameter to the user defined function.
Ans.

def checkDivisibilityBy7(number):
if number % 7 == 0:
return "Divisible by 7"
else:
return "Not divisible by 7"

num = int(input("Enter the number: "))
print(checkDivisibilityBy7(num))
2. Write a program that uses a user defined function that accepts name and gender (as M for Male, F for Female) and prefixes Mr/Ms on
the basis of the gender.
Ans.
def addPrefix(name, gender):
if gender.upper() == 'M':
return "Mr. "+ name
elif gender.upper() == 'F':
