Select rows from a DataFrame based on multiple values in a column in pandas

Question

This is not a repetitive question, yet similar to

Select rows from a DataFrame based on values in a column in pandas

In that answer up in the previous link it is only based on one criteria what if I have more than one criteria.

I would like to select many rows in a column not only one based on particular values. For the sake of argument consider the DataFrame from the World Bank

import pandas.io.wb as wb
import pandas as pd
import numpy as np
df2= wb.get_indicators()

The way I select a certian value is as so

df2.loc[df2['id'] == 'SP.POP.TOTL']

and

df2.loc[df2['id'] == 'NY.GNP.PCAP.CD']

How may I select both in one new dataframe or say 3 or 4? such that the rows are:

'SP.POP.TOTL'
'NY.GNP.PCAP.CD'

Thank you in advance

Answer 1

you may use .isin():

In [28]: df2[df2['id'].isin(['SP.POP.TOTL','NY.GNP.PCAP.CD'])]
Out[28]:
