What are python namespaces?

A Python namespace ensures that the names assigned to objects within a program are unique and can be used without conflict. In Python, namespaces are implemented as dictionaries where the object’s name serves as the key and the object itself serves as the value.

Let’s examine some examples of namespaces:

• The Local Namespace is specific to a function and contains the names defined within that function. It is created temporarily when the function is called and is cleared once the function finishes executing.
• The Global Namespace includes names from imported modules or packages that are used in the current project. It is created when the package is imported into the script and remains accessible throughout the script’s execution.
• The Built-in Namespace comprises the built-in functions provided by Python’s core, as well as specific names dedicated to various types of exceptions.
