Calls to functions, classes, modules, and packages in Python

At the beginning of the Python stage, most of the calls to functions, classes, modules, and packages are not very clear, and this essay simply explains them.

? (1) function
When the function is well defined, it can be called directly.
For example:def summ (ADD1,ADD2), then can be called directly, namely:Summ ()

(2) class
After a class is defined, it cannot be called directly as a function, but requires an indirect call.

For example:class people, then call,a=people ( object ), after,a.age () wait

(3) module

placing multiple classes under the same PY , such as in model.py , the import model can be called

(4) package

2. Create a folder under the Site-package folder, such as : Kitchen
4. other classes of . PYare put in the Kitchen file
6. in which the __init__.py file is created, an import statement is displayed, such as the file name of the From Omelet (Party omelet Class) omelet.py) Import omelet ( class name ). when programming, direct import Kitchen,kitchen.xxx can be called
