I want to make a new list from another list of words; when a certain condition of the word is met. In this case I want to add all words that have the length of 9 to a new list.

I have used :

resultReal = [y for y in resultVital if not len(y) < 4]

to remove all entries that are under the length of 4. However, I do not want to remove the entries now. I want to create a new list with the words, but keeping them in the old list.

Perhaps something like this:

if len(word) == 9:
     newlist.append()

Sorry, realized you wanted length, 9, not length 9 or greater.

newlist = [word for word in words if len(word) == 9]

Try:

newlist = []
for item in resultVital:
    if len(item) == 9:
        newlist.append(item)

Try this:

list= [list_word for list_word in words if len(list_word) == 1]
