In this project is going to make an example with pandas' library in Python.

Will see the differences between Series and DataFrame:

• Series: Is a unidimensional array with indexation. Similar to dictionary.
• DataFrame: Data structure similar to excel or SQL table.

For this example i used the "MovieLens" data set that contains information of users, films and ratings.

Prerequisites

Is necessary to install next libraries (with pip):

$ pip install pandas
$ pip install numpy
