8.5 传递任意数量的实参

8.5.1 结合使用位置实参和任意数量实参



8.5.2 使用任意数量的关键字实参



8.5 动手试一试

8-12 三明治

def make_sanwich (*toppings):
print("This sanwich adds : " + str(toppings))

make_sanwich("1")
make_sanwich("22","33","44")

8-13 用户简介

def build_profile(first , last , **user_info):
"""创建一个字典 其中包含我们知道的有关用户的一切"""
profile = {}
profile['first_name'] = first.title()
profile['last_name'] = last.title()
for key,value in user_info.items():
profile[key] = value.title()

return profile

user_profile = build_profile ('zi' , 'yi' ,
location = 'kun ming' ,
field = 'physics')
print (user_profile)

8-14 汽车

def car_information (zhizaoshang , xinghao , **car_info):
information = {}
information['zhizaoshang'] = zhizaoshang.title()
information['xinghao'] = xinghao.title()
for key,value in car_info.items():
profile[key] = value.title()

return information

car_profile = car_information ('japan' , 'xx' , )

print (car_profile)

8.6 将函数存储在模块中

8.6.1 导入整个模块







语法 module_name.function_name()

8.6.2 导入特定的函数

#导入特定的函数#

导入模块中的特定函数 语法：
from module_name import function_name

通过用逗号分隔函数名 可根据需要从模块中导入任意数量的函数 语法：
from module_name import function_0 , function_1 , function_2

对于前面 making_pizzas.py为例。如果只想导入任意数量的函数：
from pizza import make_pizza

make_pizza( )
make_pizza( )

8.6.3 使用as给函数指定别名

别名 通用语法：
from module_name import function_name as fn

from pizza import make_pizza as mp
mp( )
mp( )

8.6.4 使用as给模块指定别名

通过给模块指定简短的别名 即可轻松调用模块中的函数
import module_name as mn

import pizza as p
p.make_pizza( )
p.make_pizza( )

8.6.5 导入模块中的所有函数

#使用星号（*）运算符可让Python导入模块中的所有函数

from pizza import *

make_pizza ( )
make_pizza ( )

语法：
from moudle_name import *

8.7 函数编写指南

#函数编写指南

给形参指定默认值时 等号两边不要有空格：
def function_name (parameter_0 , parameter_1 = 'default value')

对于函数调用中的关键字实参 也应遵循这种约定
function_name(value_0 , parameter_1 = 'value')

如果形参很多，可在函数定义中输入左括号后按回车键，
并在下一行按两次Tab键，从而将形参列表和只缩进一层的函数体区分开来
def function_name (
parameter_0 , parameter_1 , parameter_2 ,
parameter_3 , parameter_4 , parameter_5 , ):
function body...
