print(cat)
print(hm_01_测试模块1.title)

import导入模块

import hm_01_测试模块1 as DogModule
import hm_02_测试模块2 as CatModule
DogModule.say_hello()
dog = DogModule.Dog()
print(dog)
CatModule.say_hello()
cat = CatModule.Cat()
print(cat)
print(DogModule.title)
print(CatModule.title)

import 同时指定别名

from hm_01_测试模块1 import Dog
from hm_02_测试模块2 import Cat
# 如果两个模块，存在同名的函数，那么导入模块的函数，会覆盖掉先导入的函数
from hm_02_测试模块2 import say_hello
from hm_01_测试模块1 import say_hello
# 不需要使用模块调用类了
dog = Dog()
print(dog)
cat = Cat()
print(cat)
say_hello()

from import

from hm_01_测试模块1 import Dog
from hm_02_测试模块2 import Cat
# 如果两个模块，存在同名的函数，那么导入模块的函数，会覆盖掉先导入的函数
# 统一写在顶部，可以使用别名as分别定义同名的函数
from hm_02_测试模块2 import say_hello as say_hello1
from hm_01_测试模块1 import say_hello as say_hello2
# 不需要使用模块调用类了
dog = Dog()
print(dog)
say_hello1()
say_hello2()

from import *(不建议使用)
函数重名没有任何的提示，出现问题不好排查

import random
rand = random.randint(1, 10)
print(random.__file__)
print(rand)
