(b) A return statement consists of the return keyword followed by an expression.
(c) Python returns immediately when it reaches a return statement .
28.1.2. A simple fruitful function
def largestinthree(a, b, c):
if a>b and a>c:
return a
elif b>c:
return b
else:
return c
# write your code here to find the largest number in a, b and c
num1 = int(input("Please enter a value for num1: "))
num2 = int(input("Please enter a value for num2: "))
num3 = int(input("Please enter a value for num3: "))
result = largestinthree(num1, num2, num3)
print("Largest of the values entered is", result)
28.1.3. Write a program to find gcd of two given numbers.
def computeGCD(x, y):
while y:
x,y=y,x%y
return x
#write your code here..
a = int(input("x: "))
b = int(input("y: "))
print (computeGCD(a, b))
