#!/usr/bin/python # -*- coding:utf-8 -*- ‘‘‘ 1.传递任意数量的实参 Python允许函数传入任意数量的实参,例如: *messages形参名中的*表示让Python创建一个空的名称为messages的元组,接收传入的所有值 ‘‘‘ def get_person_message(*messages): concat = ‘‘ for message in messages: concat += ‘ ‘ + message print "\nShow Person‘s Message:" + concat get_person_message(‘CSDN‘,‘http://blog.csdn.net/binguo168‘) get_person_message(‘http://www.cnblogs.com/binguo2008/‘) get_person_message(‘binguo‘,‘27‘,‘male‘) get_person_message(‘binguo168‘,‘27‘,‘male‘,‘basketball‘,‘football‘) ‘‘‘ 2.使用位置实参和任意数量的实参 如果函数需要接收不同类型的位置实参,需要将接收任意数量的实参放在最后。 ‘‘‘ def set_computer_configure(cpu,memory,*others): concat = ‘‘ for info in others: concat += ‘ ‘+ info print ‘cpu:‘+cpu+‘ ‘ + memory + ‘memory:‘ + ‘ ‘ +‘others:‘ +concat set_computer_configure(‘Core i7‘,‘32g‘ ,‘monitor:LG 27UD68‘,‘Display Card:GeForce GTX 1060‘) set_computer_configure(‘Intel Xeon E5-2679‘,‘128g‘ ,‘monitor:LG 27UD68‘) ‘‘‘ 3.使用任意数量的关键字实参(接收任意数量的键值对) 通过**arguname来实现接收任意数量的实参,其中两个**表示让Python创建一个空的字典,传入的所有键值对都放在这个字典中 ‘‘‘ def build_user_profile(username,**othersinfo): dict_profile = {} dict_profile[‘username‘] = username for userkey,uservalue in othersinfo.items(): dict_profile[userkey] = uservalue return dict_profile test_user_profile1 = build_user_profile(username = ‘binguo‘,age = 27,gender = ‘male‘) print test_user_profile1 test_user_profile2 = build_user_profile(username = ‘binguo168‘,hobby = ‘basketball‘,blogs = ‘CSDN‘,blog_url = ‘http://blog.csdn.net/binguo168‘) print test_user_profile2 ‘‘‘ 4.将函数存储在模块中 ‘‘‘ #导入整个模块 import importModel systemInfo = importModel.get_system_info(1) print systemInfo #导入指定的函数 from importModel import get_system_info,get_system_owner get_system_info(1) get_system_owner() #使用as对模块设定别名 import importModel as testModel testModel.get_system_info(1) #导入模块中所有的函数 from importModel import * get_system_info(1) get_system_owner()
