In this python pandas program, we will rename a column in a DataFrame using pandas library.
Steps to solve the program
- Import pandas library as pd.
- Create a dataframe using pd.DataFrame().
- Rename the Rank column to Sr.No. using df.rename(columns = {‘Rank’:’Sr.no.’}).
- Print the output.
import pandas as pd
d = {'Rank':[1,2,3,4],'Name':['Alex','John','Peter','Klaus'],'Age':[30,27,29,33],'Salary':[50000,65000,58000,66000]}
df = pd.DataFrame(d)
print(df)
df = df.rename(columns = {'Rank':'Sr.no.'})
print("New: \n",df)
Output :
0 Rank Name Age Salary
0 1 Alex 30 50000
1 2 John 27 65000
2 3 Peter 29 58000
3 4 Klaus 33 66000
New:
Sr.no. Name Age Salary
0 1 Alex 30 50000
1 2 John 27 65000
2 3 Peter 29 58000
3 4 Klaus 33 66000
