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)
