Forward Declare a Function in Python Conclusion This article will discuss whether we can implement the forward declaration in Python or not. We will also look at different ways to simulate forward declaration in Python. The Forward Declaration The forward declaration is the declaration of the sig...

A forward declaration is an identifier declaration (such as a class, function, or variable) to inform the compiler about its existence before it is defined. This allows you to use the identifier in situations where the order of declaration matters. ...
