如何添加过滤器以便我可以对向经理报告的员工分组？ 请指导我。 也让我知道下面的代码是否正确

Question

import requests
import pandas as pd
import io

"""reading url""" 
"""Creating the dataframe"""

urlData=requests.get(http://demo.rahierp.com/desk#List/Employee/List).content

df = pd.read_csv(io.StrigIO(urlData.decode('utf-8')))

 """Print the dataframe"""

 df

 """applying groupby() function to"""

"""group the data on reports_to"""

 gk = df.groupby('Reports To')

 gk


for Reports To,reports_to_df in gk:

print(Reports To)

print(reports_to_df) 

Answer 1

输入列名（ieReports_to）和你想要过滤结果的列的值

df.loc[lambda df: df.Reports_to == 'John']

output

    name manager
  0 Orid     John
  1 David    John

Answer 2

使用列表理解 -

print(df.loc[df['manager']=='LMN'])
