定义一个简单的函数，调用函数输出不同的内容

# -*- coding: utf-8 -*-

# 因为有中文注释，为了防止脚本在运行的时候提示编码错误，在脚本中需要加入上面一行代码。

# 定义一个函数，使用格式化字符串输出函数中参数的值

def cheese_and_crackers(cheese_count, boxes_of_crackers):

    print "You have %d cheeses!" % cheese_count

    print "You have %d boxes of crackers!" % boxes_of_crackers

    print "Man that's enough for a party!"

    print "Get a blanket.\n"

# 直接在函数中引用数值    

print "We can just give the function numbers directly:"

cheese_and_crackers(20, 30)

# 将两个变量赋值，然后使用函数打印出两个变量

print "OR, we can use variables from our script:"

amount_of_cheese = 10

amount_of_crackers = 50

cheese_and_crackers(amount_of_cheese, amount_of_crackers)

# 使用函数直接计算数值的和

print "We can even do math inside too:"

cheese_and_crackers(10 + 20, 5 + 6)

# 使用函数计算变量和数值的和并打印出来，在调用函数的时候引用了上面的变量

print "And we can combine the two, variables and math:"

cheese_and_crackers(amount_of_cheese + 100, amount_of_crackers + 1000)
