In this python pandas program, we will change the observation in the DataFrame using the pandas library.
Steps to solve the program
- Import pandas library as pd.
- Create a dataframe using pd.DataFrame().
- Change the age of John to 24 in the DataFrame using df[‘Age’].replace(27,24).
- Print the output.
import pandas as pd
d = {'Sr.no.':[1,2,3,4],'Name':['Alex','John','Peter','Klaus'],'Age':[30,27,29,33]}
df = pd.DataFrame(d)
print(df)
print("Change the age of John to 24:")
df['Age'] = df['Age'].replace(27,24)
print(df)
Output :
0 Sr.no. Name Age
0 1 Alex 30
1 2 John 27
2 3 Peter 29
3 4 Klaus 33
Change the age of John to 24:
Sr.no. Name Age
0 1 Alex 30
1 2 John 24
2 3 Peter 29
3 4 Klaus 33
