Question

What is the syntax to select the 'length' and 'width' columns from the DataFrame df?

Answer 1

To select the 'length' and 'width' columns from the DataFrame df, use the syntax df[['length', 'width']]. This returns a new DataFrame with just the two specified columns.

Step-by-step explanation:

To select the 'length' and 'width' columns from the DataFrame df, you would use the syntax:

df[['length', 'width']]

This will return a new DataFrame containing only the columns 'length' and 'width'. In Pandas, which is a library used in Python for data manipulation and analysis, you can select multiple columns from a DataFrame by passing a list of column names to the DataFrame object. It is important to use double square brackets when you want to select multiple columns, which indicates that you're passing a list.
