please help solve the python problem, thank you

Carry on Pythonlsta def count_carries(a, b): Two positive integers a and b can be added together to produce their sum with the usual integer column-wise addition algorithm that we all learned back when we were but wee little children. Instead of the sum a+b that the language could compute for you anyway, this problem asks you to count how many times there is a carry of one into the next column caused by adding the two digits in the current column (possibly including the carry from the previous column), and return that total count. Your function should be efficient even when the parameter integers a and b are enormous enough to require thousands of digits to write down. To extract the lowest digit of a positive integer n, use the expression n810. To extract all other digits except the lowest one, use the expression n//10. You can use these simple integer arithmetic operations to execute the steps of the column-wise integer addition so that you don't care about the actual result of the addition, but only the carry produced in each column. Expected result 99999 1 11111111111 2222222222 123456789 987654321 2**100 2**100 - 1 13 3**1000 3**1000 + 1 243
