Pythonic
Introduction to Pythonic Coding
The term “Pythonic” doesn’t have a formal definition, but it is widely accepted among the Python community as a descriptor for code that follows the philosophy and guiding principles intrinsic to the Python language. This philosophy is famously captured in the Zen of Python, a collection of 20 aphorisms by Tim Peters, a long-time Python developer.
To view the Zen of Python, you can use the following command in your Python interpreter:
The Zen of Python emphasizes code readability and simplicity over complexity, extensibility, and succinct expressions.
Why Writing Pythonic Code Is Important
Writing Pythonic code helps to maintain program clarity and simplicity, which in turns aids in debugging and code maintenance. Code written in a Pythonic style tends to be more readable and concise, making it easier to understand and share with others.
Consider the following examples in which the Pythonic approach simplifies code:
Example 1: List Comprehension
Non-Pythonic Way:
Pythonic Way:
List comprehension provides a compact and readable way of handling operations on list elements. It represents the spirit of Pythonic code.
Example 2: Enumerate Function
Non-Pythonic Way:
Pythonic Way:
Here, the Pythonic code uses the built-in function enumerate()
. It is a more readable and efficient way of handling iterable indexing.
Note
Pythonic doesn’t mean using Python functionality and idioms without understanding them. It is always essential to understand the logic behind the code you write.
Conclusion
Writing Pythonic code is a skill worth mastering for every Python programmer. It not only makes your code elegant and readable but also reduces complexity. The Zen of Python serves as great guiding principles to understand the philosophy underlying Pythonic coding practices. Remember, simplicity is the ultimate sophistication.
