How to assign a unique code based on keywords in Python?

Question

I am trying to assign a predetermined code based on keywords in a string.
For example: ‘Repaired computer per tech manual’ ‘Cleaned connector and now it works’

If ‘repair’ then input in new column ‘R1’. If ‘cleaned’ input ‘C1’

Ultimately I want to assign a code based on multiple keywords. Such as ‘repaired computer’ = R1, ‘repaired wire’ = R2, etc.

I tried .find then .replace but it doesn’t seem to be the right answer. Eventually I want to put this to work on data frames with 150k+ rows.

I’m using SpaCy for preprocessing and could find anything that would meet my above needs. I am new to Python/NLP/coding so much could be rookie mistakes. Figured I’d try the community for help.

Thanks in advance!!
