# LEARNER CODE START HERE
words = file_contents.split(" ")
words_list = []

frequency={}
file_contents=file_contents.split()
for word in words:
    for uninteresting_word in uninteresting_words:
        if word is not uninteresting_word:
            words_list.append(word)
for word in words_list:
    if not word.isalpha():
        word =''.join([letter for letter in word if word.isalpha()])
words_dict = {}
for word in words_list:
    if word not in words_dict.keys():
        words_dict[word] = words_list.count(word)

#wordcloud
cloud = wordcloud.WordCloud()
cloud.generate_from_frequencies(words_dict)
return cloud.to_array()
