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.

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.

Everytime I wanted to do some quick automation I always choose python because it is simple, relatively easy, and fast enough to do the automation. This has saved me a lot of painful time if I were to do it myself manually. I also like java and currently learning some C.

For years, Python is my default language of choice when solving computing problems in general. I'm a member of Python Venezuela.

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.

Former Google SRE. While at Google, I was a Python readability reviewer and loved it! Since then I've tried to stay current with python 3, but there's always something new to learn...

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

Python fits with how I think and allows me to quickly write powerful, maintainable, and extensible code.
