Pandas Objects

Before we dive into series, let’s do a quick recap of pandas ‘objects’. At the core of the pandas library there are two fundamental data structures/objects:

• Series

• Data Frames

What is Series?

• A one dimensional labeled array

• Can hold data of any type

• Are like a column in a table

What can a Series have?

• A Series can have all the elements as numbers in it

• A Series can have all the elements as strings in it

• A Series can have its elements as both numbers and strings.

• But the data type of the Series is always ‘object’ in this case

• Series is like a list in Python which can take any type of value like integer, strings, float (or decimal value), etc

• All the items in series are labeled with indexes

• By default indexing starts from 0 in Series.

Human vs Python Index

• Indexes that we (Human) understand

• Indexes that Python Understand

Well, it all starts with ‘0’. That’s the only difference.

Create a Series

• Remember to import library before using it!

  import pandas as pd

• You can create your own Series using list

• You can create your own Series using a dictionary
