# Split up and expand the columnrental_rate_expanded = rental_rate_str.____.____("____", expand=True)

The code you're asking for is used to split a column in a pandas DataFrame. Here's how you can do it:

# Split up and expand the column
rental_rate_expanded = rental_rate_str.str.split(" ", expand=True)

In this code:

• rental_rate_str is the column you want to split.
• str.split(" ", expand=True) is the function used to split the column. The argument " " is the delimiter that separates the values in the column. In this case, it's a space. The expand=True argument means that the function should return a DataFrame with the split values in separate columns. If expand=False, it would return a Series with lists of split values.
