How to check if my list has an item from another list(dictionary)?

Question

I\'m a beginner in programming with python, and I\'ve got a question which may have an easy answer.

So I have a dictionary of words which is imported from a .txt file, n

Answer 1

Here's a one-liner using for, that generates a set of mispelled words:

mispelled = { word for word in sentence if word not in dictionary }

I've renamed your variables for clarity

Answer 2

Using sets

You could use sets to find all of the words not in the dictionary list.

>>> set([1,2,3]).difference([2,3])
set([1])

Note that this will not include duplicates.

So for you, it would be something like this (if you need the result to be a list):

misspelled_word_list = list( set(sentence_list).difference(words) )

Using for

Since you are required to use for, here is an alternate (less efficient) approach:

misspelled_word_list = []
for word in sentence_list:
    if (not word in misspelled_word_list) and (not word in words):
        misspelled_word_list.append(word)

You just loop over the words in sentence_list and check whether they are in your words list or not.
