1. Initialise a variable bigWords to be an empty list
2. iterate through the list of words
2.2 if current word is bigger than four (Hint: use len function) append to bigWords
3. Return bigWords

There are better methods.

def remove_long_words(lwords):
    ## lwords == list of words
    
    for elem in lwords:
        if len(elem) > 4:
            ## if pop at the index of the element location
            lwords.pop(lwords.index(elem))
    
    return lwords
