In python, The function count_contains_x takes a list of strings (wordList) and returns the count of how many strings in the list contain at least one upper- or lower-case 'x'. Hint: Use the accumulator pattern to accumulate the count. Hint: You might want to use the string method count. For example: Test Result strlist = ["xerox", "OXEN", "whiffleball", "XOXOX"] print(count_contains_x(strlist)) 3 fish = ["angel", "gold", "cat", "puffer", "damsel"] print(count_contains_x(fish)) 0 strlist = ["X", "x"] print(count_contains_x(strlist)) 2 list_of_one_x = ["x"] print(count_contains_x(list_of_one_x)) 1

Question

In python, The function count_contains_x takes a list of strings (wordList) and returns the count of how many strings in the list contain at least one upper- or lower-case 'x'.

Hint: Use the accumulator pattern to accumulate the count.

Hint: You might want to use the string method count.

For example:

Test Result
strlist = ["xerox", "OXEN", "whiffleball", "XOXOX"] print(count_contains_x(strlist)) 3
fish = ["angel", "gold", "cat", "puffer", "damsel"] print(count_contains_x(fish)) 0
strlist = ["X", "x"] print(count_contains_x(strlist)) 2
list_of_one_x = ["x"] print(count_contains_x(list_of_one_x)) 1
