练习19:给函数传参的多种方式

def cheese_and_crackers(cheese_count, boxes_of_crackers):
print "You have %d cheese!" % cheese_count
print "You have %d boxs 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) # 直接传数值，字符串等

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) # 传变量作为参数

print "We can even do math inside too:"
cheese_and_crackers(10 + 20, 5 + 6) # 传运算式为参数

print "And we can combine the two, variables and math:"
cheese_and_crackers(amount_of_cheese +100, amount_of_crackers + 1000)
