According to Python's documentation:
" A scope is a textual region of a Python program, where a namespace is directly accessible."
Directly accessible means that when you're looking for an unqualified reference to a name, Python tries to find it in the namespace.
Scopes are determined statically, but actually, during runtime, they are used dynamically. This means that by inspecting the source code, you can tell what the scope of an object is, but this doesn't prevent the software from altering that during runtime. There are four different scopes that Python makes accessible (not necessarily all of them are present at the same time, of course):
- The local scope, which is the innermost one and contains the local names.
