str对象没有属性random*python2.7*

Question

我写了这篇文章，很明显我搞砸了。在

我在第57行和第38行出现了错误（实际上每当它试图给变量itemname分配一个新名称时）

import random

def createitem():

    weapon = ['sword', 'dagger', 'axe']
    armor = ['cloth armor', 'chainmail', 'leather armor', 'full plate']

    magicpre = ['shining', 'burning', 'aether', 'fine']
    magicsuf = ['of the bear', 'of the wolf', 'of the jackal']
    magictag = '*MAGIC*'

    rarepre = ['angelic', 'demonic', 'blessed', 'cursed', 'masterwork']
    raresuf = ['of heaven', 'of hell', 'of the king', 'of the chimera']
    raretag = '*RARE*'

    pendingitem = []

    itemname = ''

    appenditem = pendingitem.append(itemname)

    aq = random.randint(0,5)


    for num in range(0, aq):

        weporarm = random.randint(0,1)
        raritycheck = random.randint(0,5)
        preorsuf = random.randint(0,1)

        if weporarm == 1:
            if raritycheck == 5:
                itemname = raretag, random.choice(rarepre), random.choice(armor), random.choice(raresuf)
            elif raritycheck == 4 and preorsuf == 2:

    appenditem
    a = str(pendingitem)
    print('Your inventory:', a)

Answer 1

这两行上有一个句点（.），而不是逗号（,），这导致python将它后面的random解释为前一个变量的属性，当然，这是失败的。在

itemname = magictag, random.choice(magicpre), random.choice(armor). random.choice(magicsuf)
# Here                              -^

只要用逗号代替它，你就可以了：

^{pr2}$
