Sort description in English:

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. We'll see how transform the Movielens data set to a DataFrame, and work with this structure similarly to work as a database.
