Given two integral numbers in string format, we have to define a function that can receive these numbers, convert into integers and return the sum as integer in Python.

Example:

    Input:
    num1 = "10"
    num2 = "20"

    Function calling:
    calculateSum(num1, num2)

    Output:
    Sum = 30

Logic:

  • Input two numbers in string format (We are just assigning the hard-coded values here), note that, numbers should be integral type.
  • Define a function, pass these values as parameters.
  • Explicitly convert the values to integer by using int(variable/value).
  • Calculate the sum and return it.

Program:

# function to calculate and return the sum
# parameters:
# a, b - integral numbers in string format
# return: sum of the numbers in integer format

def calculateSum (a,b):
	s = int(a) + int(b)
	return s 

# Main code 
# take two integral numbers as strings
num1 = "10"
num2 = "20"

# calculate sum
sum = calculateSum (num1, num2)

# print sum
print "Sum = ", sum

Output

    Sum =  30
