For example, you can add a new column to calculate the total cost of an item by multiplying the price by the quantity. This can be done using the following code:
import pandas as pd
# create a sample DataFrame
data = {'Name': ['John', 'Mary', 'David'],
'Price': [10.5, 20.8, 30.2],
'Quantity': [2, 3, 4]}
df = pd.DataFrame(data)
# add a new column to calculate the total cost
df['Total Cost'] = df['Price'] * df['Quantity']
print(df)
10 Easy Ways To Add A New Column To Your Pandas Dataframe
Here are 10 easy ways to add a new column to your Pandas DataFrame:
