How do I define constants in code?

To define constants in code, you typically use the const keyword in languages like JavaScript or C++. For example, in JavaScript, you can write const PI = 3.14;.

Are there any best practices for naming constants?

Yes, it's best to use uppercase letters with underscores for constants, like MAX_VALUE or DEFAULT_TIMEOUT, to distinguish them from variables.

Can I define constants in classes?

Absolutely! In many programming languages, you can define constants within classes using the static keyword. For example, in Java: public static final int MAX_USERS = 100;.

What about defining constants in Python?

In Python, while there isn't a built-in constant type, you can define constants by convention using uppercase variable names, like PI = 3.14, and avoid changing their values.
