In Python, The function add_char_counts takes three parameters: a string s and two strings of length 1, char1 and char2, and returns the total number of times either char1 or char2 appears in s.  For example, the word "scallions" has 2 s's and 1 n, so add_char_counts("scallions", "s", "n") returns 3. Hint: Use a string method to help solve this problem (count).

Question

In Python, The function add_char_counts takes three parameters: a string s and two strings of length 1, char1 and char2, and returns the total number of times either char1 or char2 appears in s. 

For example, the word "scallions" has 2 s's and 1 n, so add_char_counts("scallions", "s", "n") returns 3.

Hint: Use a string method to help solve this problem (count).  You do not need an accumulator.

 

For example:

Test Result
print(add_char_counts('Indiana', 'a', 'b')) 2
print(add_char_counts('BAHAMAS', 'A', 'B')) 4
print(add_char_counts('Mississippi', 'i', 'M')) 5
print(add_char_counts("spam spam spam spam", "s", "p")) 8
