python - import 与 from X import *

特别简单.

如果你有2个文件,在另一个文件B中引用第一个文件A,直接 

from A import * 即可.

例如;

class Hi():
    def instance_say_hi(self):
        print(f'-- self: {self}')
        return "hi"
    
    @classmethod
    def class_method_say_hi(this_class):
        print(f'-- this_class: {this_class}')
        return "hi from class_method_say_hi"
    
    @staticmethod
    def static_method_say_hi():
        return "hi from static_method_say_hi"

在第二个文件中, 直接:

from Hi import *
hi = Hi()
