Python for: Data Science

Python  Python is an open source scripting language.  Developed by Guido Van Rossum in late 1980s  Named after Monty Python comedy group.  Python supports multiple programming paradigms, including object-oriented, imperative and functional programming or procedural styles.

Who uses Python?  Google : Many components of the Google spider and search engine are written in Python.  Yahoo Groups  Yahoo Maps  Battlefield 2  Civilization 4  Walt Disney Feature Animation  National Weather Service  Red Hat  Pardus  And many more…

Why Do Data Scientists Love Coding in Python?

1. Large community = Documentation = Brainpower - W ith Python, you can find a large (and still growing!) active community. If you get lost you can rely on a this large community of experts to help you find a proper solution for questions related to Data Science and Data Analysis.  Thorough and complete:  Official Tutorial:  Language Reference:  Daily round-up of py news. Active user engagement.  Pythonware Daily:  Planet Python:  A very high chance of python related query getting answered in seconds! As is StackOverflow.  Irc Node:  StackOverflow: stackoverflow.com/questions/tagged/python?sort=neweststackoverflow.com/questions/tagged/python?sort=newest

2. Growing Data Analytics Libraries:  Scientific Computing: NumPy, SciPy, Pandas, IPython Notebook  Machine Learning: Scikit-learn, Shogun, PyLearn2  Plotting and Visualization: matplotlib, ggplot, plotly

3. IPython-Notebook  The IPython Notebook is an interactive computational environment, in which you can combine code execution, rich text, mathematics, plots and rich media, as shown in this example session :

4. Easy to learn & Concise: Syntax is user friendly, consistent and elegant.  Generally, Python code is 70% shorter than the same in Java.  Python has a better and easier syntax than other OO languages.

How to Install Python:  How to Install Python?  Go to:  Choose appropriate installer according to you OS, download and install it.  Bam! You’re done. (Demo Some Code)

More on Conciseness:  Box Plot in Java using JFreeChart library :
