The usage of import in Python

In Python, the import statement is used to bring in modules or specific functions and classes from within modules.

1. Import the entire module.
2. Bring in the module named module_name.
3. This imports the entire module into the current namespace, allowing you to access the module’s properties, functions, classes, etc. using module_name.
4. Import specific functions or classes from a module.
5. Import the function and class from the specified module.
6. This allows you to directly import specific functions or classes from a module without having to access them using the module name.
7. Rename the imported module or function.
8. use the alias to import the module
   import specific function from module with an alias
9. You can assign an alias to imported modules or functions using the “as” keyword, allowing you to refer to them by the alias in your code.
10. Import all content in the module.
11. import all functions from module_name
12. Using * wildcard to import all functions, classes, etc. from a module is possible but generally not recommended due to potential namespace clutter and naming conflicts.
13. Importing submodules in a module.
14. import the submodule_name from the module_name.
15. If a module contains multiple submodules, you can import the submodules in this way.

It is important to note that import statements for modules are usually placed at the beginning of the file, and multiple modules can be imported with one module per line.
