纯小白，求大佬告知下这个是什么情况，运行不下去

用pycharm学习写的这一段代码，结果运行不出来.
代码：
def cheese_and_crackers(cheese_count, boxes_of_crackers):
    print(f"You have {cheese_count} cheeses!")
    print(f"You have {boxes_of_crackers} boxes of crackers!")
    print("Man that's enough fon 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 = 50

    cheese_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 abd math:")
    cheese_and_crackers(amount_of_cheese + 100, amount_of_crackers + 1000)
运行结果：
