OK, I need you to finish writing a function for me. The function disemvowel takes a single word as a parameter and then

i am not passing this challenge

disemvowel.py 
word = "Treehouse"
vowells = ["a", "e", "i", "o", "u"]
final_result = []

def disemvowel(word):
    for letter in word:
        if letter.lower() or letter.upper() not in vowells:
            final_result.append(letter)
        else:
            continue              
        return final_result

You have the right idea but there a few errors to fix

  • the return statement is indented to far. This causes the function to return after completing the first pass through the for loop
  • final_list is a constructed as a list, but a string is expected. Use "".join() to create the string
  • the challenge checker runs the function many times, but final_list is initialized only once. This causes results from one test to be added to the next test. Move the initialization inside the function
  • the logic of the if condition is not correct. Each side of the or must be complete comparisons. Simply having letter.lower() before the or will return a letter which is always considered "truthy" making the append happen every time. You could add a check for the lowered letter in the vowell list but since letter.upper() will never be found in the vowels list, the full if condition can be reduced to checking whether the lowered lettered is in the list.

Post back if you need more help. Good luck!!!

i did these corrections:

def disemvowel(word):
    word = "treehouse"
    vowells = ["a", "e", "i", "o", "u"]
    final_result = []
    for letter in word:
        if letter.lower() not in vowells:
            final_result.append(letter)
        else:
            continue              
    return final_result"".join()

And here is what i am getting now Bummer! SyntaxError: invalid syntax (disemvowel.py, line 10)

Almost there. Two more errors:

  • the syntax error in line 10: final_result should be the argument to the join function
  • delete the assignment word = "treehouse" as it overwrites the argument passed into the function.
