Even though there might be several unique namespaces specified, it may not be possible to access all of the namespaces given because of scope. The concept of scope refers to a segment of the program from where we access the namespace directly without any prefix. The following are the scope types:
i. Scope containing local names, current function.
ii. Scope containing global names, the scope of the module.
iii. Scope containing built-in names of the outermost scope.
