海外TECH	DEV Community	What is "Pythonic" coding?	https://dev.to/sid_am_ahd935/what-is-pythonic-coding-27cm	What is quot Pythonic quot coding Numerous articles which teach python and it s libraries usually refer their code as not being Pythonic enough when reviewing it But what does it actually mean Let s explore it in this article Python is one of the most popular languages which is both easy to learn and complex enough to build a fully functional app in any field It is a dynamically typed interpreted language which even though is built for higher readability has its own perks One of them is it s unique method of writing and structuring the code using a syntax exclusive to only Python itself When a programmer declares a snippet as not Pythonic enough they basically mean that the code is either a literal translation from another language or that the code can be made more readable by using the inherent features of Python Two examples are given to illustrate the concept further Tuple PackingIn Python if there are a numbers of constants and values separated by a comma then the Python interpreter automatically takes it as a collection data type known as tuple This is commonly known as packing This packing utility is commonly used when we have to pass or receive a number of arguments but don t have a specific collective data type in mind to use So for temporary cases tuple packing does a brilliant job in wrapping up these small use cases without much effort def sum multiply power x y a x y b x y c x y return a b cans sum multiply power print ans gt gt gt Similar to packing Python also has tuple unpacking through which we can extract elements of a collection data type into individual variables without any extra effort or hassle ans ans ans ansprint The first part of ans is ans print The second part of ans is ans print The third part of ans is ans gt gt gt The first part of ans is gt gt gt The second part of ans is gt gt gt The third part of ans is Also when passing in values to and fro a function or a variable unpacking an element can also be done using the asterisk operator def print birds a b c print At first comes a print Then comes b print And lastly comes c blues Jake Jay Jim print birds blues gt gt gt At first comes Jake gt gt gt Then comes Jay gt gt gt And lastly comes Jim List ComprehensionsList comprehensions are a unique way to add update values inside a list data type and it also helps in creating a new list using values from a different list List comprehension makes it much more readable and also reduces the complexity in understanding the working of the loops List without using comprehension evens for i in range if i evens append i List created using comprehension evens i for i in range if i List updated using comprehension odds i for i in range if i odds num for num in odds Another use case of list comprehension which comes in pretty handy is that it can also be used to call functions while iterating over a list of values def pretty print val print The value of this variable is val pretty print num for num in odds evens print num for num in odds if odds gt In short there is no limit to the Pythonic way of coding Newer versions introduce new techniques structure and methods for writing the same logic in more readable and more comprehensive manner The best way to learn this coding style is to look into the Python documentations provided with each new version released and experiment with using different implementations for same logic	2022-08-14 16:33:28
