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.

This track uses Python 3. It is highly recommended that students upgrade to at least Python 3.6 as some features used by this track may not be supported in earlier version of Python.

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.

Python was among the first programming languages I started learning, and since then I've used it for fun, in an academic setting, as well as in my work life.

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.

I've been using and enjoying Python in both hobby as well as professional projects for a few years now. Yet, I never cease to be amazed about how Python programs can be concise without being obfuscated or cryptic.

I appreciate python among the many languages I have used for expressiveness and readability. I have used it at work and for personal projects.

Although Python wasn't my first -- and won't be my last -- programming language, it remains my favorite for introducing others to the joys, the pains, the infrequent ecstacies, and the occasional terrors of life before the REPL.
