Conditional If Statement: If value contains string then set another column equal to s
I have a column 'original_title', where I have different film titles i.a. all films of Star Wars (+ the name of the episode) and Star Trek (+ the name of the episode). I want to create one column which will show me only 'star trek' (without the name of episode), 'star wars' and 'na'.

This is my code for the new column:
df['Trek_Wars'] ="Star Wars"), "star_wars","Star Trek"), "star_trek"))
However, it doesn't work

ValueError Traceback (most recent call last) in () 1 df['Trek_Wars'] ="Star Wars"), "star_wars", ----> 2"Star Trek"), "star_trek"))

ValueError: either both or neither of x and y should be given
What should I do?
df is a dictionary? Please show structure.

It's a DataFrame from Pandas.
