Local Scope. A variable created inside a function belongs to the local scope of that function, and can only be used inside that function.

This summarizes not only the Python scope levels but also the sequence of steps that Python follows when resolving names in a program. In this tutorial, you’ll learn: What scopes are and how they work in Python; Why it’s important to know about Python scope; What the LEGB rule is and how Python uses it to resolve names

Feb 9, 2021 · Scope of Objects in Python : Scope refers to the coding region from which a particular Python object is accessible. Hence one cannot access any particular object from anywhere from the code, the accessing has to be allowed by the scope of the object. Let’s take an example to have a detailed understanding of the same: Example 1:

Nov 15, 2008 · It's a confusing world for intermediate Python programmers.
