Exercise 4: Write a program to add two numbers and print the result Ex: 20 + 30 => 50
Solution:
Concept:
print() with two arguments, string and an arithmetic expression
print("Sum of 20 and 30 is :", 20 + 30)
Output:
Sum of 20 and 30 is : 50
Exercise 5: Write a program to add two numbers and print the result Ex: 20 + 30 => 50
Solution:
Concept:
Handling user inputs, arithmetic operation,
use of int() type constructor, string format() usage.
a = int(input("Enter first number :>"))
b = int(input("Enter second number :>"))
#explicit use of int() type constructor
#a = int(a)
#b = int(b)
print("sum of {} and {} is {}".format(a,b,a+b))
Output:
Enter first number :>10
Enter second number :>50
sum of 10 and 50 is 60
