Practical Data Science using Python - Pandas Series 2

The video tutorial covers the basics of series indexing in pandas, focusing on methods like LOC and ILOC for accessing elements. It explains various series attributes, such as data types and handling missing values, and demonstrates advanced operations like typecasting and date range generation.

What is the primary purpose of using index values in a Pandas series?

• To sort the series

• To extract elements from the series

• To change the data type of the series

• To merge two series

Which function is used to access elements in a series using explicit index values?

• iloc

• loc

• iat

• append

What does the IAT indexer do in a Pandas series?

• Extracts multiple elements

• Extracts a single element

• Adds two series

• Checks for null values

Which attribute would you use to convert a series into an array?

• array

• values

• dtype

• axis

How can you determine if a series contains any null values?

• Using the is_unique attribute

• Using the is_monotonic attribute

• Using the hasnas attribute

• Using the dtype attribute

What does the is_monotonic attribute check in a series?

• If the series contains null values

• If the series values are monotonically increasing

• If the series values are unique

• If the series is sorted

Which attribute would you use to find out the number of elements in a series?

• values

• axis

• dtype

• size

What is the prerequisite for adding two series using the add function?

• Both series must have the same number of elements

• Both series must be sorted

• Both series must contain no null values

• Both series must have the same data type

How can you append one series to another in Pandas?

• Using the iloc method

• Using the loc method

• Using the append method

• Using the add method

What does the date_range function in Pandas do?

• Adds two date series

• Converts dates to strings

• Generates a list of dates and timestamps

• Sorts a series by date
