Python

Join the Python Track
Python is a clear and powerful object-oriented programming language with an elegant and easy-to-read syntax. It is ideal for prototyping and ad-hoc tasks, but also sees wide use in scientific computing, web development, and automation.

About Python

prices = {'apple': 0.75, 'egg': 0.50}
cart = {
  'apple': 1,
  'egg': 6
}

bill = sum(prices[item] * cart[item]
           for item in cart)

print(f'I have to pay {bill:.2f}')

Python is a strong language for beginners.

There are many resources available for programmers of all levels, the code is highly readable, and in many cases phrases are comparable to those in the English language.

Code can be written and executed from the command line, in an interactive IPython session, or in a Jupyter (IPython) notebook.

The most common form of Python is compiled in C; this is often invisible to the beginning programmer, but if there are uses for which exceptionally fast implementation is needed then C extensions can be written to optimize Python execution.

Python is used extensively in scientific computing, finance, games, networking, internet development, and in assembling pipelines of other programs.

Python was started by Guido van Rossum in 1989; its name is an homage to the comedy troupe Monty Python.

Python 2 is used widely but support may end by 2020; it is highly recommended that beginners use Python 3 (they are similar, but users will encounter some differences).

Python development is shepherded by The Python Software Foundation and there are active community-based user groups worldwide.

I really like the ability to look at other people's solutions.

I'm working through the F# and Python tracks at the moment. Really like the ability to look at other people's solutions. I've had some helpful comments from others too.

Relaxed. Encouraging. Supportive.

I am a physics student with interest and experience in computational methods, especially using Python. I would like to help others learn to use its expressive syntax and extensive libraries to facilitate clean and speedy development.

Although not my first programming language, Python made me fall in love with programming. I never looked back since.

I've been using C# for personal projects in Unity for a little over a year and love the balance it strikes between readiblity and functionality.
Fun. Challenging. Interesting
