The main advantage of this approach, however, is that you only have to store one dataset record in memory at a time. Reading datasets in this way is slow and places all of the responsibility for extracting individual data items of information from the records on the programmer. When we read a csv dataset in base Python we did so by opening the dataset, reading and processing a record at a time and then closing the dataset after we had read the last record. We can easily create a Pandas Dataframe by reading a. We will mainly be looking at the Dataframe.

Each column in a pandas Dataframe is a pandas Series data structure. The Series equates in general to a vector or a list. There are two main data structure used by pandas, they are the Series and the Dataframe. Import pandas as pd Pandas data structures

In almost all examples of Python code using the pandas library, it will have been imported and given an alias of pd. Importing the pandas library is done in exactly the same way as for any other library. If you are wondering why I write pandas with a lower case вЂpвЂ™ it is because it is the name of the package and Python is case sensitive.

Joining of datasets (after they have been loaded into Dataframes).

Aggregating data using data grouping facilities using the split-apply-combine paradigm.

Inserting and deleting columns from data structures.

Reshaping data (long -> wide, wide -> long).

Slicing and subsetting data in Dataframes (tables!).

Reading data stored in CSV files (other file formats can be read as well).

Particular features of pandas that we will be looking at over this and the next couple of episodes include: Most of the things that pandas can do can be done with basic Python, but the collected set of pandas functions and data structure makes the data analysis tasks more consistent in terms of syntax and therefore aids readabilty. Pandas is a Python library containing a set of functions and specialised data structures that have been designed to help Python programmers to perform data analysis tasks in a structured way.
