In practice, you can override .__setattr__() to prevent all attribute reassignments and make your attributes immutable. Here’s how you can override this method to create a class that works as a namespace for your constants: Python >>> class ConstantsNamespace: ... PI = 3.1415926535897...
In general, it’s a good practice to avoid functions that modify global variables. If possible, try to write self-contained functions with an explicit return statement that returns a coherent and meaningful value.Remove ads Using return With ConditionalsPython functions are not restricted to having...

Python String Module Python String module contains some constants, utility function, and classes for string manipulation. String contains substring? Python provides two common ways to check if a string contains another string. Python String startswith() Python string startswith() function returns True...
These settings are more stringent than the defaults provided by the SSLContext constructor, and may be adjusted in the future, without prior deprecation, if best-practice security requirements change. The new recommended best practice for using stdlib libraries that support SSL is to use create_...

Constants and Globals For constants, Python developers typically useuppercase letterswith underscores to separate words. An example constant isMAX_SIZE. This approach immediately signals that the value is constant and not meant to change. Global variablesshould be named cautiously to avoid naming confli...
The use of global variables should be minimized in favor of local variables, as global variables can lead to unexpected behavior and make it harder to understand and debug code. It’s generally a good practice to use local variables within functions, and to pass any necessary values as argumen...
Avoid mutable global state. 2.5.1 Definition Module-level values or class attributes that can get mutated during program execution. 2.5.2 Pros Occasionally useful. 2.5.3 Cons Breaks encapsulation: Such design can make it hard to achieve valid objectives. For example, if global state is used to...
