Question

我已经减少了代码，只显示了我认为与以下错误相关的部分。这是在python 3.x中完成的，因为我正在尝试自学，所以我没有任何python 2.x的经验

谢谢！

Traceback (most recent call last):
File "rpcombat_refactored.py", line 306, in <module> shopping = buy_equipment()
File "rpcombat_refactored.py", line 242, in buy_equipment

File "rpcombat_refactored.py", line 94, in join_with_and elif sequence < 1:
TypeError: unorderable types: list() < int()

代码：

def join_with_and(sequence):
    if len(sequence) > 1:
        last_item = sequence[-1]
        sentence = ", ".join(sequence[:-1])
        sentence = sentence + " and " + last_item
    elif sequence < 1:
        sentence = "whole lot of nothing"
    else:
        sentence = sequence[0]
    return sentence

def buy_equipment():

    # Omitting item list
    # Omitting purchase prompt

    # If the item is in stock and the player has enough gold, buy it
    if purchase in stock:
        if stock[purchase][0] <= profile['gold']:
            test_phrase = profile['Name'] + " buys themself some equipment"
            print(fix_gender(profile['Gender'],test_phrase))
            print("You buy a", purchase, "for", stock[purchase][0], "gold    pieces.")
            profile['gold'] -= stock[purchase][0]
            profile['inventory'].append(purchase)
            print("You have a", join_with_and(profile['inventory']), "in  your bag.")
            print("You have", profile['gold'], "left.")
        else:
            print("You don't have enough gold to buy that.")
    elif purchase == 'done' or purchase == "":
        return profile['inventory'] == [] and profile['gold'] > 10
    else:
        print("We don't have", purchase, "in stock.")
    return purchase

您的generate_rpc方法未返回个人资料。它什么都不返回。所以profile是无。
