Regular expression is one of many programming choices you can use to solve this problem.

Let assume that we have 4 words: apple pineapple applepine pineapplepine. If you use the following pattern of regEx:

/\w*apple\w*/g -- You can match the whole word that contain a word “apple” in “apple” “pineapple” “applepine” and “pineapplepine”

/\w*apple/g -- You can match the whole word that contain a word “apple” in “apple” and “pineapple”

/apple\w*/g -- You can match the whole word that contain a word “apple” in “apple” and “applepine”

/apple/g -- You can match the whole word that contain a word “apple” in “apple” ONLY.

You can use a regular expression.

import re
result = re.findall(r'\w*apple\w*', # apple, surrounded by zero or more word symbols
                     'I got a pineapple, I got a pen.', # input string
                     re.I # optional: make search case insensitive
                    )

>>> result
['pineapple']

Convert that particular string to a list using split(), iterate over the list and Do a string match using in.

lst = ['apple', 'pineapple', 'fruit', 'applephone']
for i in lst:
    if 'apple' in i:
        print(i)

apple
pineapple
applephone
