python - remove() returns None when I try to remove a variable from a list

Question

I am working on a part of a program that turns a statement into a question.

When I try to remove x it returns None. I want it to print the sentence with that item removed, what am I doing wrong?

def Ask(Question):
    Auxiliary = ("will", "might", "would", "do", "were", "are", "did")
    for x in Auxiliary:
        if x in Question:
            Question_l = Question.lower()
            Question_tk_l = word_tokenize(Question)
            Aux_Rem = Question_tk_l.remove(x)
            print (Aux_Rem)

Example for behaviour wanted:

"what we are doing in the woods"

should become

"what we doing in the woods"

I want to remove any auxiliary word from question.

Answer 1

That's correct behaviour. remove removes that element and doesn't return a value (i.e. returns None). You can use pop if you wish to access the removed element.
