Question

Primary arithmetic. Write a program (called q that adds two numbers and counts the number of carry operations. You will define your own user-defined functions for this problem. Your solution must make use of at least two user-defined functions to receive full credit Programming tips. There are a number of different ways to tackle this problem. Consider first working on printing out the addition equation as shown in the following examples. Then, work on computing the number of carries required for the addition. Finally, a built-in function that you may find useful to incorporate in your program is max For example, to find the maximum of 3 numbers a4, 198, and -3, use the max (54, 198 34), which returns 198.

Explanation / Answer

number1 =input('enter number1')
number2 =input('enter number2')

def check_length(number1,number2):
    if len(number1) == len(number2):
        pair_list = zip(number1,number2)
        pair_list.reverse()
        return pair_list
    else:
        if len(number1) > len(number2):
            dif = len(number1) - len(number2)
            number2 = '0'*dif + number2
        else:
            dif = len(number2) - len(number1)
            number1 = '0'*dif + number1
        pair_list = zip(number1, number2)
        pair_list.reverse()
        return pair_list

def carry_count (pair_list):
    count = 0
    result = 0
    for i,j in pair_list:
        if int(i) + int(j) + int(count) > 9:
            count = 0
            result = result + 1
            count = str(int(i) + int(j))[0]
    return result

zip_list = check_length(str(number1),str(number2))
output = carry_count(zip_list)
print 'carry count is ',output
