def getUser():  def关键字定义了一个函数

关键字实参

def getUser(userName, userAge):

getUser(userName='张三', userAge=18)

默认值

def getUser(userName, userAge=18):   如果没有传年龄过来默认年龄等于18

经过测试,python和Java一样只有值传递没有引用传递

def make(*args1, **args2)    *任意数量实参  **任意数量关键字实参

import pizza  导入模块

pizza.make() 使用其他模块的方法

from moudle_name import function_name1,function_name2,function_name3 导入某个模块的具体方法 可以导入多个

from moudle_name import function_name1 as fun1 用as去给这个方法起别名

import moudle_name as m1  用as给模块起别名

from moudle_name import * 导入这个模块所有的方法
