Pandas - Check if a column contains a substring of a string

Question

Let's say I have this example Series ser:

ser = pd.Series(["gmail", "yahoo", "office"])

and the following string: t = "mail@mail.com"

I want to check if any of the values in the Series is a substring of the string t.

For the other way around it's very easy (ser.str.contains(t)), but what's an efficant way to do my way?

Thanks

any(s in t for s in ser)

Answer 2

您可以使用any或all ：

any(x in t for x in ser)

all(x in t for x in ser)
