Python In Practice - 15 Projects to Master Python - Slicing Columns, Rows, and Values from Pandas DataFrames

The video tutorial explains how to work with Pandas DataFrames, focusing on selecting columns, adding new columns, and updating indexes. It covers accessing rows and columns using loc and iloc, and demonstrates slicing and indexing techniques. The tutorial also shows how to extract specific values from a DataFrame, drawing parallels with NumPy array slicing.

What is the primary method to select a specific column from a Pandas DataFrame?

• Using parentheses

• Using angle brackets

• Using square brackets

• Using curly braces

How can you add a new column to an existing DataFrame?

• By using the add_column method

• By directly assigning values to a new column name

• By using the insert method

• By using the append method

Which method is used to access a specific row by its label in a DataFrame?

• iloc

• loc

• select

• get_row

What is the purpose of the iloc method in Pandas?

• To delete columns

• To access rows and columns by label

• To access rows and columns by integer index

• To insert new rows

How can you retrieve a single value from a DataFrame using a method similar to NumPy array slicing?

• By using the slice method

• By using the get_value method

• By using the extract method

• By using the values attribute with index positions

What is the correct way to access the values of a DataFrame as a 2D array?

• Using the get_array method

• Using the array method

• Using the values attribute

• Using the to_numpy method

Which method allows you to access a DataFrame's row by its implicit index?

• iloc

• index

• loc

• get_row
