# Python: Count the number of carry operations for each of a set of addition problems

## Python Basic - 1: Exercise-31 with Solution

Write a Python program to count the number of carry operations for each of a set of addition problems.

According to Wikipedia " In elementary arithmetic, a carry is a digit that is transferred from one column of digits to another column of more significant digits. It is part of the standard algorithm to add numbers together by starting with the rightmost digits and working to the left. For example, when 6 and 7 are added to make 13, the "3" is written to the same column and the "1" is carried to the left".

Pictorial Presentation: Sample Solution:

Python Code:

``````def carry_number(x, y):
ctr = 0
if(x == 0 and y == 0):
return 0
z = 0
for i in reversed(range(10)):
z = x%10 + y%10 + z
if z > 9:
z = 1
else:
z = 0
ctr += z
x //= 10
y //= 10

if ctr == 0:
return "No carry operation."
elif ctr == 1:
return ctr
else:
return ctr
print(carry_number(786, 457))
print(carry_number(5, 6))
``````

Sample Output:

```3
1
```
