In Python, constants are typically used to represent values that should not be changed during the execution of a program. Although Python doesn't have a built-in constant type, it is a common practice to use uppercase letters and underscores to represent constants in a clear and readable manner. This tutorial will guide you through the conventions and best practices for naming constants in Python.
Follow the PEP 8 style guide when naming constants in Python. According to PEP 8:
Let's create a simple Python script to demonstrate the use of constants and the naming convention.
In the above example, we have defined three constants: GRAVITY, SPEED_OF_LIGHT, and planet names (EARTH, MARS, and JUPITER). The names are in uppercase letters with underscores, making them easily distinguishable as constants.
To use constants defined in one module in another module, you can simply import them.
In this example, we import the constants from the constants module and use them in the main.py module to calculate the weight on Earth.
Readability: Using uppercase letters and underscores enhances code readability, making it clear that a variable is intended to be a constant.
Consistency: Following a consistent naming convention across your codebase makes it easier for developers to understand and maintain the code.
Avoiding accidental changes: Constants are meant to be unchangeable. By convention, using uppercase letters signals to other developers that the value should not be modified.
Following a consistent naming convention for constants in Python is essential for writing clean, readable, and maintainable code. The use of uppercase letters and underscores helps distinguish constants from other variables and makes your code more understandable to both yourself and others.
