What are some examples of namespaces in Python?

In Python, namespaces are containers that hold a collection of identifiers (names) and their corresponding objects. Examples include local, global, and built-in namespaces.

Can you explain local and global namespaces with examples?

Sure! A local namespace is created when a function is called, containing the names defined within that function. A global namespace contains names defined at the top level of a module. For example:

x = 10  # Global namespace

def my_function():
    y = 5  # Local namespace
    return x + y

What about built-in namespaces?

Built-in namespaces contain names that are always available in Python, such as print(), len(), and int(). These are accessible from any part of your code.

How do namespaces help avoid naming conflicts?

Namespaces help avoid naming conflicts by allowing the same name to exist in different contexts. For example, you can have a variable named x in a function and another x in the global scope without any issues.
