Creating C like Enum in Python

Creating C-like enums in Python can be a useful technique when you want to define a set of named integer constants that represent discrete values. Unlike Python's built-in enum module, which is more Pythonic and versatile, C-like enums are simple and lack some features like the automatic assignment of integer values.
In Python, you can create C-like enums using class constants. Here's a step-by-step tutorial with a code example:
Create a Python class to represent your C-like enum. Each value in the enum is defined as a class constant (an attribute) within the class. Typically, you'll use uppercase letters for these constant names to indicate they are meant to be constants.
Now that you've defined your C-like enum, you can use it in your code. You access the enum values using the class constants.
Readability: Using C-like enums can make your code more readable by giving meaningful names to integer constants, making it clear what each value represents.
Maintainability: If you need to change the values associated with your constants, you can do so in one place (the enum class) without affecting the rest of your code.
Preventing Magic Numbers: Instead of using "magic numbers" (hardcoded integer values) throughout your code, you can use enum constants to make your code more self-explanatory.
Safety: Since Python doesn't support strict typing, using enums can help prevent unintentional reassignment or modification of constant values.
Here's a complete example using the enum class and a simple function:
When you run this code, it will produce the following output:
This tutorial covers the basics of creating C-like enums in Python. Remember that while this approach can provide enum-like behavior in Python, it lacks some of the features and safety checks offered by Python's built-in enum module. Depending on your needs, you might consider using the enum module for more robust enum functionality in Python.
