Explanation:
A new column bonus is created by doubling the value in the column salary.
Intuition​
I will use the pandas library to solve this problem. I will create a new column bonus by multiplying the salary column by 2.
Solution Code​
- Python
import pandas as pd
def createBonusColumn(employees: pd.DataFrame) -> pd.DataFrame:
employees['bonus'] = employees['salary']*2
return employees
