Python isnt clumsy or random, as JavaScript. The Zen of Python emphasizes the importance of readability, simplicity, clarity, consistency, and good coding practices. Apparently there is a 20th, but I’m focusing on understanding the written list before speculating on what the. For example, the variants package turns functions into namespaces of "related functionality." It is a good example of how the Zen of Python can inspire new abstractions. Python has been around for 30 years, and its popularity only seems to grow as it ages. The Zen of Python is a list of 19 general truths for Python design principles. thezenofpython-1 Beautiful is better than ugly. Indeed, some third-party modules take this guideline and run with it. pep20-thezenofpython Author: Tim Peters Created : 1 Post history: 2 Long time Pythoneer Tim Peters succinctly channels the BDFL’s guiding principles for Python’s design into 20 aphorisms, only 19 of which have been written down. operator accesses an object, which in turn will usually, but not always, do some sort of dictionary lookup, makes Python hard to optimize, but easy to explain. If you enter any more modern Python interpreter and then type import this.
Functions have access to their local namespace, their parent namespace, and the global namespace. In this first lesson, I want to introduce you to The Zen of Python by Tim Peters.
RTHE ZEN OF PYTHON CODE
(The interpreter is the program that translates Python code into binary and executes it.) To find it, just type import this in the Python interpreter. This means that correctly predicting module semantics often just requires familiarity with how Python namespaces work. Tim Peters wrote a poem called The Zen of Python. In short, the guiding principles of The Zen of Python can be summarized as follows: Write code that is easy to read and understand. It should help in developing program that is easy to understand, modify, and maintain. Though simple, they are sparse data structures-which is often the best way to achieve a goal.Ī namespace is a mapping from names to objects. The Zen of Python emphasizes the importance of readability, simplicity, clarity, consistency, and good coding practices.
RTHE ZEN OF PYTHON SERIES
As we wrap up our series on the Zen of Python, I see how namespaces provide a similar service. Its a set of expressions which corners the spirit of the language. Is this a reference to the famous Dutch computer scientist Edsger W. Its one of the many aspects that adds to the awesomeness of Python. Python's Zen states on line 14 that: Although that way may not be obvious at first unless you're Dutch. The shamos is the candle that lights all the others: it is the only candle whose fire can be used, not just watched. The Zen of Python saw light for the first time in 1999.
