How do you import a module into Python? Provide different ways to import modules.

Importing modules in Python: Exploring different methods

Python imports modules using the "import" statement. A module can be imported in a variety of ways depending on how you want to access its functions, classes, or variables. Here are the different ways to import modules:

Basic import:

import module_name

The above command imports the entire module and allows you to access its contents using the module name as a prefix. For example, if the module contains a function named "is_even()", you can access it as module_name.is_even().

Import with alias:

import module_name as alias

This imports the entire module but assigns it an alias. This allows you to access the module's contents using the alias instead of the full module name. For example, if you use "import date as dt", you can access the date.today() function as dt.today().

Import all items:

from module_name import *

This imports all items from the module directly into your current namespace. Using this approach can cause naming conflicts and make it difficult to track imported items' origins.

Conditional import:

if condition:
   import module_name

This allows you to conditionally import a module based on a certain condition. The "import" will occur only if the condition is true.

Import submodules:

import package_name.module_name

If a module is part of a package (i.e., it is in a subdirectory with an init.py file), we can import it using the full path from the package. For example, if we have a package named "testpackage" and a module named "testmodule" inside it, we can import it as "import testpackage.testmodule".
