b) if a new product d is introduced and it sells 90 units, what would be the best way to add this information to the existing df dataframe in python? (7 points)
Answer
Explanation:
Step1: Import pandas library
import pandas as pd
Step2: Create a new DataFrame row
new_row = pd.DataFrame({'Product': ['D'], 'Units Sold': [90]})
Step3: Concatenate the new row with the existing DataFrame
df = pd.concat([df, new_row], ignore_index=True)
Answer:
The steps above show how to add the information about product D selling 90 units to an existing df DataFrame in Python. First import the pandas library. Then create a new DataFrame row representing product D and its sales. Finally, use pd.concat to combine the new row with the existing DataFrame and reset the index.
