Different ways to import modules in Python with example wpaccuracy

In Python, there are several ways to import modules. Here are the three most common ways:

1. Import the entire module:

import module_name

This will import the entire module and allow you to access its functions and variables using the syntax module_name.function_name or module_name.variable_name.

2. Import specific functions or variables from a module:

from module_name import function_name, variable_name

This will import only the specified functions or variables from the module and allow you to access them directly using their names, without needing to prefix them with the module name.

3. Import the entire module with an alias:

import module_name as alias_name

This will import the entire module, but give it a shorter name, which you can then use to access its functions and variables.

For example, if you import the “numpy” module with an alias of “np”, you can access its functions and variables using the syntax np.function_name or np.variable_name.

There are also other less commonly used ways to import modules, such as importing all the functions and variables from a module using the * wildcard character (from module_name import *), or dynamically importing modules using the importlib module.
