How to check if any word of string match another string

Question

I'm trying to find some function in Python which can help me with finding some word-matches of two different strings.

For example we have 2 strings:

"I am playing basketball everyday"
"basketball is the worst game ever"

And I want this function to return true if "basketball" was found in both strings.

You can always use `in`. For example, `"basketball" in "I love basketball"` returns `True` — Riccardo Bucco, Dec 19 '19 at 15:33
Another approach would be to use list(set(string_1.split()) & set(string_2.split())) which would return all words found in both strings — DanStu, Dec 19 '19 at 15:35

You can find which are the common words in two phrases:

common_words = set(phrase1.split()).intersection(phrase2.split())

You can check if a word is in both phrases by simply checking if it is in the common_words set (example: if word in common_words: ...).

You can also check how many elements this set has. If len(common_words) == 0 then phrase1 and phrase2 contain no common words.

l = ["I am playing basketball everyday", "basketball is the worst game ever"]

for x in l:
  print (x)
  if "basketball" in x.lower():
    print (True)

str1 = "I am playing basketball everyday"
str2 = "basketball is the worst game ever"

if "basketball" in str1 and "basketball" in str2:
    print "basketball is in both strings!"
