here is my code...
new_word=input("Enter a word to remove the vowels: ")
new_word=list(new_word)
no_vowels=[]
def remove_vowels(word):
for letter in word:
if letter=='a' or letter=='e' or letter=='i' or letter=='o' or letter=='u':
word.remove(letter)
else:
no_vowels.append(letter)
remove_vowels(new_word)
print(no_vowels)
when I input "cat", it only prints "c" instead of "ct" can't figure out why

Avoid altering a term being used for iteration.
When you change an iterable inside a loop, you can cause side effects like elements being skipped over. There are several safe alternatives, including building a new term instead of altering the original, and iterate using a copy of the term that will be altered.
