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.

The track also improved my ability to understand a problem and form questions around it

I started with the Python track which helped me to better understand the language's syntax and data structures. The track also improved my ability to understand a problem and form questions around it so that I was able to find or learn what I needed to in order to find a solution.

Relaxed. Encouraging. Supportive.

Python is my natural go-to language for a lot of things. I translate lots of its concepts into other languages. I believe everyone needs a language that can really 'clear' their head when working.

Python is one of my favorite languages. I fell in love with it seeing the beautiful absence of brackets and semi-colon. I also love it for list comprehension and its extensive use in Machine Learning and Raspberry Pi. I think everyone should learn Python!

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.

I have a sysadmin background (on Linux and Windows) and I began learning Python about a year ago to automate tasks. I really like the breadth of the use that you get in this language, and how easy is to write clean code.
Fun. Challenging. Interesting
