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
Find Duplicate Rows based on all columns To find & select the duplicate all rows based on all columns call the Daraframe. duplicate() without any subset argument. It will return a Boolean series with True at the place of each duplicated rows except their first occurrence (default value of keep argument is 'first').
Use DataFrame. drop_duplicates() to Drop Duplicate and Keep First Rows. You can use DataFrame. drop_duplicates() without any arguments to drop rows with the same values on all columns.
you may use .isin():
In [28]: df2[df2['id'].isin(['SP.POP.TOTL','NY.GNP.PCAP.CD'])]
Out[28]:
