Fortunately, with pandas, we can use the powerful python ecosystem. Considering how to solve such troublesome data problems, I would like to conduct some fuzzy text matching to determine the correct value.
Fortunately, others have already done a lot of work in this area. The fuzzy wuzzy library contains some useful functions to solve such problems. First, make sure that you have installed him.

Quickly write an example to test the idea:
Copy Code code as follows:
