PYTHON BASICS What is a LIST and a DICTIONARY SERIES DATAFRAME Introduction Tutorial Beginner Course
This is part 1 of a 2 part video where we discuss what is a series and a dataframe. Before we understand what is a series and dataframe, we need to understand two data structures in Python: the list and the dictionary.
We will be discussing how each element in a list can be referenced using its index position, and how a list can be composed of multiple sub-lists to create a two-dimensional list, which is what we will be using to construct a dataframe.
We will discuss how a Python dictionary is structured using the key and value pairs and how this relates to the concept of a dataframe.
