Question

res = dict(filter(lambda item: search_key in item[0], dict1.items()))
list_keys = [ k for k in res ]

Here is my code. I want it to only include the list of words, not any additional concatenation with the exception of - ,"cats" like I am searching cat I want the list not to return catspoon .

Answer 1

Use a regular expression to match whole words.

import re

search_key = r'\bcat\b'
res = dict(filter(lambda item: re.search(search_key, item[0]), dict1.items()))
list_keys = [ k for k in res ]
