def cheese_and_crackers(cheese_count, boxes_of_crackers): # 定義一個有兩個引數的函式
print(f"You have {cheese_count} cheeses!")
print(f"You have {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:" )#直接給數字引數
cheese_and_crackers(20,30)
print("OR,we can use variables from our script:") # 通過變數給引數
amount_of_cheese = 10
amount_of_crackers = 50
cheese_and_crackers(amount_of_cheese,amount_of_crackers)
print("We can even do math inside too:") # 還可以用算式作為引數
cheese_and_crackers(10 + 20, 5 + 6)
print("And we can combine the two, variables and math:" ) #兩個相結合既有變數又有運算
cheese_and_crackers(amount_of_cheese + 100, amount_of_crackers + 1000)
