Python Pandas TypeError: First Argument Must Be String Or Compiled Pattern

I am sorry for the super easy question, but I can't make it work I am cleaning data and want to add a flag, if the name (which is seperate into two columns First and Last Name) is

Solution 1:

IF you are trying to look for both regex patterns- as in search for both ? and tourist in the string. you can use the | operator. So change pattern to

pattern = "tourist|\?"

This will check if a question mark OR if 'tourist` is in the string

If you ever want to check regex, pythex is a really good place. I made a test one for you.
