Question

我不确定为什么我得到一个空列表我测试了这个函数。有人可以帮我解决这个问题吗？

def find_images_with_keyword(key_dict, keywords_list):
'''(dict of {str: list of str}, list of str) -> list
Given a keyword_dictionary and a list of keywords,
return the list of filenames associated with the given keywords.
The list of filenames should include all filenames having one or more
of the specified keywords(ie, a filename may be associated with only one,
not all of the keywords in the list).
>>> find_images_with_keyword({'dog': ['1.png', '2.png'], 'animal': ['1.png',  '3.png']}, ['dog', 'animal'])
  ['1.png', '2.png', '3.png']
'''
new_list = []
for keyword in key_dict.items():
    for filename in keywords_list:
        if keyword == filename:
            new_list.append(filename)
return new_list
