Sorting list based on values from another list?

Question

I have a list of strings like this:

X = [\"a\", \"b\", \"c\", \"d\", \"e\", \"f\", \"g\", \"h\", \"i\"]
Y = [ 0,   1,   1,   0,   1,   2,   2,   0,   1 ]
         


        

Answer 1

You can create a pandas Series, using the primary list as data and the other list as index, and then just sort by the index:

import pandas as pd
pd.Series(data=X,index=Y).sort_index().tolist()

output:

['a', 'd', 'h', 'b', 'c', 'e', 'i', 'f', 'g']
