How to customize modules in python

The Python module is a Python file, ending with .py, which includes Python object definitions and Python statements, making Python code segments more logical and easier to use. Easier to understand. Since Python modules have so many benefits, how to reference Python modules?

Define module

Create a new folder to store the module to be defined, and then create a py file under the folder. This py file is the module we define

import statement

Custom modules can be introduced using the import statement. The steps are to import the module first, and then call the functions contained in the module. Custom modules can be imported The module is placed in the current directory to facilitate interpreter path search. The following is an example of importing a custom hello.py module and calling the World function:

Import module

import hello

Now you can call the functions contained in the module

support.print_func("World")

The output result is: Hello World!

The above example can also be implemented using the from...import method, which refers to importing the specified part from a module into the current namespace. The above function can be written as:

from hello import World

If you want to All contents in the module are imported into the current namespace. You can use the from...import* method. The specific example is as follows:

from hello import *

Also note that when a module is to be imported, the Python interpreter will determine the location of the module. To search, the specific search order is as follows:

1. Current directory

2. If it is not in the current directory, Python will search every directory under the shell variable python path

3. If neither is found, Python will check the default path
