Pandas: Insert a column at a specific index in a given DataFrame
Pandas Indexing: Exercise-22 with Solution
Write a Pandas program to insert a column at a specific index in a given DataFrame.
Sample Solution:
Python Code :
import pandas as pd
df = pd.DataFrame({
'school_code': ['s001','s002','s003','s001','s002','s004'],
'class': ['V', 'V', 'VI', 'VI', 'V', 'VI'],
'name': ['Alberto Franco','Gino Mcneill','Ryan Parkes', 'Eesha Hinton', 'Gino Mcneill', 'David Parkes'],
'weight': [35, 32, 33, 30, 31, 32]},
index = [1, 2, 3, 4, 5, 6])
print("Original DataFrame with single index:")
print(df)
date_of_birth = ['15/05/2002','17/05/2002','16/02/1999','25/09/1998','11/05/2002','15/09/1997']
idx = 3
print("\nInsert 'date_of_birth' column in 3rd position of the said DataFrame:")
df.insert(loc=idx, column='date_of_birth', value=date_of_birth)
print(df)
Sample Output:
Original DataFrame with single index: school_code class name weight 1 s001 V Alberto Franco 35 2 s002 V Gino Mcneill 32 3 s003 VI Ryan Parkes 33 4 s001 VI Eesha Hinton 30 5 s002 V Gino Mcneill 31 6 s004 VI David Parkes 32 Insert 'date_of_birth' column in 3rd position of the said DataFrame: school_code class name date_of_birth weight 1 s001 V Alberto Franco 15/05/2002 35 2 s002 V Gino Mcneill 17/05/2002 32 3 s003 VI Ryan Parkes 16/02/1999 33 4 s001 VI Eesha Hinton 25/09/1998 30 5 s002 V Gino Mcneill 11/05/2002 31 6 s004 VI David Parkes 15/09/1997 32
