In a programming language, scope refers to the area where a function or variable is visible and accessible to other code. Below are some common terms associated with scope: Global scope refers to a global or public space. Local scope refers to a local or restricted region.

In Python, the concept of scope is closely related to the concept of the namespace. As you’ve learned so far, a Python scope determines where in your program a name is visible. Python scopes are implemented as dictionaries that map names to objects. These dictionaries are commonly called namespaces.
