How to test if a string contains one of the substrings in a list, in pandas?

Question

Is there any function that would be the equivalent of a combination of df.isin() and df[col].str.contains()?

For example, say I have the s

Answer 1

You can use str.contains alone with a regex pattern using OR (|):

s[s.str.contains('og|at')]

Or you could add the series to a dataframe then use str.contains:

df = pd.DataFrame(s)
df[s.str.contains('og|at')] 

Output:

0 cat
1 hat
2 dog
3 fog
