selecting rows based on multiple column values in pandas dataframe

Question

I have a pandas DataFrame df:

import pandas as pd

data = {\"Name\": [\"AAAA\", \"BBBB\"],
        \"C1\": [25, 12],
              


        

Answer 1

I like to use df.query() for these kind of things

df.query('C1>=0 and C1<=20 and C2>=0 and C2<=20 and C3>=0 and C3<=20')
