# 定义cheese_and_crackers这个函数,该函数有两个参数，分别是cheese_count 和boxes_of_crackers.
# 函数其实就是个print的集合
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")
#屏幕上首先显示下一行的语句。

print("We can just give the function numbers directy:")
# 调用了这个函数，带入两个参数（20, 30）
cheese_and_crackers(20,30)
print("OR,we can use variables from our script:")
# 定义两个变量
amount_of_cheese=10
amount_of_crackers=50
#将定义的两个变量作为参数引入到函数中。

cheese_and_crackers(amount_of_cheese,amount_of_crackers)
print("We can even do math inside too:")
# 引入的参数是一个运算式
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)
