what's thrown me off was unbalance parentheses, eg high_and_low("4 5 29 54 4 0 -214 542 -64 1 -3 6 -6"), "542 -214") ... there are two closing parentheses. Why do all the asserts have this pattern?

hmmm. all test cases pass but when i submit, i get an error
Time: 68ms Passed: 6 Failed: 0
Test Results:
Basic Tests (6 Passed, 0 Failed)
STDERR:

IndexError: string index out of range

Was the no-arg Python test resolved? I can't get it to work.

Test.assert_equals(get_count(None),{"vowels":0,"consonants":0},'Should return 5 vowel and 0 consonants')???

if None, should rethrn 0 vowels, no?
