How are the standard libraries organized in Python in terms of scope: global namespace or within their own modules?

In Python, standard libraries are organized within their modules and packages, each of which has its own namespace. This means that functions, classes, and variables of the standard library are located inside modules and are accessible through import.

The global namespace in Python is the namespace of the current module or script, not the entire interpreter. Standard libraries are not loaded automatically into the global namespace; they need to be explicitly imported.

For example:

import math
print(math.sqrt(16))  # sqrt is a function from the math module

Thus, standard libraries are isolated within their modules, which prevents name conflicts and improves code structure.
