I am getting error of sum of two nos. the output should give addition of two numbers,but instead it is displaying 2 nos. side-by-side.I have pasted the program and output for the same. print "Please give a number: " a = input() print "And another: " b = input() print "The sum of these numbers is: " print a + b output should be a=21,b=21, a+b=42 whereas it is showing 2121. |

In Python 3.1, the input() function always returns a string. In your
case, the string is "21". Adding two strings together gives you a
longer string: "12" + "34" --> "1234".
To get your program to do what you want, convert the string to a number
using int():
a = int(input('give a number: '))
b = int(input('and another: '))
print('the sum is', a + b)
