# 定义cheese_and_crackers 函数

# 第一种输出：直接打印数字
print "We can just give the function numbers directly:"

# 第二种输出：函数变量单独赋值
print "OR, we can use variables from our script:"
amount_of_cheese = 10
amount_of_crackers = 50

# 第三种输出：相加
print "We can even do math inside too:"
cheese_and_crackers(10 + 20, 5 + 6)

# 第四种输出：数字和变量相加
print "And we can combine the two, variables and math:"
cheese_and_crackers(amount_of_cheese + 100, amount_of_crackers + 100)

# 第五种输出：相加的相加
print "And there is another:"

amount_of_crackers = B + 50
cheese_and_crackers(amount_of_cheese, amount_of_crackers)

# 第六种输出：变量的变量，运行错误！
