Thousands of people from different fields have learned Python, and so can you. It’s just a language, and a way of thinking in terms of rules, systems and patterns. There is no magic involved! With a bit of time and effort you too can become fluent in Python.
Some quick facts about Python
The Python programming language was developed by Guido van Rossum in the late 1980s at the Centrum Wiskunde & Informatica in The Netherlands.
Python is a high-level programming language with emphasis on readability. ‘High level’ means that it is distant from the 0s and 1s from the computer, and closer to human language (English, in this case).
Python is free/open-source software and is available for all major platforms.
Because Python is a dynamic programming language (executed at runtime), it is also often used as a scripting language in various kinds of applications.
Why is Python called Python?
The name ‘Python’ was inspired by the the British comediants group Monty Python.
Python and typeface design
Python plays an important role in type design and font production. Most font editors today support scripting with Python.

Python 2 vs. Python 3
Python 3 is a new version of Python which is not fully compatible with the 2.X branch. Some of the new features in Python 3 have been ported backwards to Python 2.6 and 2.7, and are available via the
Python 3 is still not the default version in many production environments, since several important libraries have not been updated. Many systems still come with some version of Python 2.X pre-installed (for example, as of writing, the latest version of macOS comes with Python 2.7.2).
Python’s Design Philosophy
According to Guido van Rossum, the following guidelines helped to make decisions while designing and implementing Python:
- Borrow ideas from elsewhere whenever it makes sense.
- “Things should be as simple as possible, but no simpler.” (Einstein)
- Do one thing well (The “UNIX philosophy”).
- Don’t fret too much about performance – plan to optimize later when needed.
- Don’t fight the environment and go with the flow.
- Don’t try for perfection because “good enough” is often just that.
- (Hence) it’s okay to cut corners sometimes, especially if you can do it right later.
The Zen of Python
The philosophy behind the design of the Python language is summarized in a series of aphorisms called The Zen of Python. This text is available as an ‘easter egg’ in all Python distributions. Simply type the following line of code in your favorite Python console:
…and the complete version of The Zen of Python will be printed as output:
>>> Beautiful is better than ugly. >>> Explicit is better than implicit. >>> Simple is better than complex. >>> Complex is better than complicated. >>> Flat is better than nested. >>> Sparse is better than dense. >>> Readability counts. >>> ...
