Naming conventions in Python guide naming variables, functions, classes, and other identifiers. These practices enhance code readability and help maintain consistency across projects. They align with PEP 8, the official Python style guide, which suggests standards for naming across the Python standard libraryand other codebases.
Understanding Python naming conventions is essential for readability and maintainability. These conventions define how to name variables, functions, classes, and more, following guidelines like snake_case and PascalCase.
In Python, naming conventions are crucial for creating readable and maintainable code. Descriptive and meaningful names help us understand the purpose of variables and functions, while consistency in naming helps avoid confusion.
Naming conventions in Python play a crucial role in writing clear and maintainable code. Special cases in naming can impact the way code is understood and used. This section focuses on underscores in function and variable names and the differences between public and internal interfaces.
Python encourages a clean and readable coding style. Topics such as indentation, line wrapping, and documentation practices are important. They help developers create code that is easy to read and maintain.
Python class names follow specific conventions to foster clarity and consistency in code. These guidelines are part of Python’s broader style guide, known as PEP 8. One primary rule is using CapWords, also called UpperCamelCase. This means capitalizing each word in the class name without using underscores. For example, MyClassName or Animal. Clear ...
In Python, naming conventions are crucial for creating understandable and maintainable code. Variables often use snake_case. This means all letters are in lowercase, and underscores represent spaces between words. Example: Python variable names must begin with a letter (a-z, A-Z) or an underscore (_), but they cannot start with a number. They can i...
In Python, global variables are defined outside of any function or block. Multiple functions within the program can access these variables. According to the PEP 8 style guide, global variable names should be in lowercase with words separated by underscores. This style is known as snake_case. Here’s an example: Consistencyis key. While PEP 8 provide...
Local variables in Python follow specific naming conventions to improve code clarity. Python’s style guide, known as PEP 8, suggests using snake_case for local variable names. This means using lowercase letters and underscores to separate words. For example, local_variablemakes it clear and readable. These names need to be descriptive. A good name ...
In Python, function names should clearly convey the function’s purpose. This helps programmers understand the function’s role in a program. Python uses snake_case for naming functions. This means using lowercase letters, with words separated by underscores (_). For example: Function names should be descriptive but not too long. Aim for clarity whil...
Nov 29, 2023 · In this tutorial, you'll learn a few Python naming conventions involving single and double underscores (_). You'll learn how to use this character to differentiate between public and non-public names in APIs, write safe classes for subclassing purposes, avoid name clashes, and more.
- Single Leading Underscore: _var. When it comes to variable and method names, the single underscore prefix has a meaning by convention only. It’s a hint to the programmer—and it means what the Python community agrees it should mean, but it does not affect the behavior of your programs.
- Single Trailing Underscore: var_ Sometimes the most fitting name for a variable is already taken by a keyword. Therefore names like class or def cannot be used as variable names in Python.
- Double Leading Underscore: __var. The naming patterns we covered so far received their meaning from agreed upon conventions only. With Python class attributes (variables and methods) that start with double underscores, things are a little different.
- Double Leading and Trailing Underscore: __var__ Perhaps surprisingly, name mangling is not applied if a name starts and ends with double underscores.
Oct 8, 2024 · What is Naming Conventions in Python? Naming conventions in Python refer to rules and guidelines for naming variables, functions, classes, and other entities in your code. Adhering to these conventions ensures consistency, readability, and better collaboration among developers.
Jul 5, 2001 · Variable names follow the same convention as function names. mixedCase is allowed only in contexts where that’s already the prevailing style (e.g. threading.py), to retain backwards compatibility. Function and Method Arguments

Feb 16, 2022 · Python uses many dunder variables to convey information about objects to us (and to convey information back to itself). Below are a few common dunder variables you might want to access yourself. Classes use these dunder attributes: __name__: stores their name. __dict__: stores their attributes (see where attributes are stored)
