I was just getting into Python programming. I wrote a simple program to calculate sum of two user-input numbers:
a,b = input("enter first number"), input("enter second number")
print("sum of given numbers is ", (a+b))
Now if I enter the numbers as 23 and 52, what showed in the output is:
sum of given numbers is 23 52
What is wrong with my code?

input() in Python 3 returns a string; you need to convert the input values to integers with int() before you can add them:
a,b = int(input("enter first number")), int(input("enter second number"))
(You may want to wrap this in a try:/except ValueError: for nicer response when the user doesn’t enter an integer.
