笨方法学习Python-习题19: 函数和变量

# coding=utf-8def 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")print("We can just give the function numbers directly: ")cheese_and_crackers(20,30)print("OR,we can use variables from our script: ")amount_of_cheese = 10 amount_of_crackers = 50cheese_and_crackers(amount_of_cheese,amount_of_crackers)print("We can even do math inside too: ")cheese_and_crackers(10+20,5+6)print("And we can combine the two,variables and math: ")cheese_and_crackers(amount_of_cheese+100,amount_of_crackers+1000)"""的函数 cheese_and_crackers 很多的参数，然后在函数里把它们打印出来。我们可以在函数里用变量名，我们可以在函数里做运算，我们甚至可以将变量和运算结合起来。从一方面来说，函数的参数和我们的生成变量时用的 = 赋值符类似。事实上，如果一个物件你可以用 =将其命名，你通常也可以将其作为参数传递给一个函数。"""
