Introduction 👋

What is Pandas in Python?

Pandas is the most famous python library providing fast, flexible, and expressive data structures designed to make working with "relational" or "labeled" data both easy and intuitive. It aims to be the fundamental high-level building block for doing practical,real world data analysis in Python. Additionally, it has the broader goal of becomingthe most powerful and flexible open source data analysis / manipulation tool available in any language. It is already well on its way towards this goal.

In Pandas, the data is usually utilized to support the statistical analysis inSciPy, plotting functions fromMatplotlib, and machine learning algorithms inScikit-learn.

Main Features

Here are just a few of the things that pandas does well:

  • Easy handling ofmissing data (represented asNaN) in floating point as well as non-floating point data
  • Size mutability: columns can beinserted and deleted from DataFrame and higher dimensional objects
  • Automatic and explicitdata alignment: objects can be explicitly aligned to a set of labels, or the user can simplyignore the labels and letSeries,DataFrame, etc. automatically align the data for you in computations
  • Powerful, flexiblegroup by functionality to perform split-apply-combine operations on data sets, for both aggregatingand transforming data
  • Make iteasy to convert ragged, differently-indexed data in other Python and NumPy data structuresinto DataFrame objects
  • Intelligent label-basedslicing,fancy indexing, andsubsetting oflarge data sets
  • Intuitivemerging andjoining datasets
  • Flexiblereshaping andpivoting of datasets
  • Hierarchical labeling of axes (possible to have multiple labels per tick)
  • Robust IO tools for loading data fromflat files (CSV and delimited),Excel files,databases,and saving/loading data from the ultrafastHDF5 format
  • Time series-specific functionality: date range generation and frequency conversion, moving window statistics,moving window linear regressions, date shifting and lagging, etc.

Core Components of Pandas Data Structure

Pandas have two core data structure components, and all operations are based on those two objects. Organizing data in a particular way is known as a data structure. Here are the two pandas data structures:

  • Series
  • DataFrame

Install Pandas Module:

Open yourAnaconda Promptpropmt and type and run the following command (individually):

  •   pip install pandas

Once Installed now we can import it inside our python code.


Frequently asked questions ❔

How can I thank you for writing and sharing this tutorial? 🌷

You canStar Badge andFork Badge Starring and Forking is free for you, but it tells me and other people that it was helpful and you like this tutorial.

Gohere if you aren't here already and click ➞✰ Star andⵖ Fork button in the top right corner. You'll be asked to create a GitHub account if you don't already have one.


How can I read this tutorial without an Internet connection?GIF

  1. Gohere and click the big green ➞Code button in the top right of the page, then click ➞Download ZIP.

    Download ZIP

  2. Extract the ZIP and open it. Unfortunately I don't have any more specific instructions because how exactly this is done depends on which operating system you run.

  3. Launch ipython notebook from the folder which contains the notebooks. Open each one of them

    Kernel > Restart & Clear Output

This will clear all the outputs and now you can understand each statement and learn interactively.

If you have git and you know how to use it, you can also clone the repository instead of downloading a zip and extracting it. An advantage with doing it this way is that you don't need to download the whole tutorial again to get the latest version of it, all you need to do is to pull with git and run ipython notebook again.
