python中包的用法

先给一个简单的例子:
这是文件的结构:

run.pypackage| -- __init__.py| -- fun1.py| -- fun2.py

run.py

from package.fun1 import fun1from package.fun2 import fun2fun1()fun2()

fun1.py

def fun1():  print("fun1 is being used")

fun2.py

def fun2():  print("fun2 is being used")

init.py置空, 用于标识当前文件夹是一个包\

输出结果

fun1 is being usedfun2 is being used
