Question

我已经创建了这个函数，使我能够输入引号和作者，然后将它们腌制成.txt文件。

然而，似乎我可能仅限于在执行“enterquote”功能时我最终覆盖的一行腌制信息。我似乎无法弄清楚如何在文件中放入更多信息。

我怎么能这样做？

 def readquote():
    f = open("quote.txt","r")
    pquote = pickle.load(f)
    pauthor = pickle.load(f)
    print "%3s\n - %s" % (pquote, pauthor)

def enterquote():
    f = open("quote.txt","w")
    quote = raw_input("What quote has its place in the quote book? \n to quit press Q\n\n")
    if quote != "Q":
        pickle.dump(quote, f)
        author = raw_input("what author said that? \n to quit press Q \n\n")
        pickle.dump(author, f)
        if author == "Q":
            print "goodbye"
    elif quote == "Q":
        print "goodbye"
    f.close()

我用架子试过这个：

def readquote():
    f = shelve.open('quote.txt')
    psaying = f[quote["saying"]]
    pauthor = f[quote["author"]]
    for key in quote :
        print "%3s\n - %s" % (psaying, pauthor)


def enterquote2():
    f = shelve.open('quote.txt')
    quote = {}
    quote["saying"] = raw_input("What quote has its place in the quote book? \n to quit press Q\n\n")
    if quote != "Q":
        f['saying'] = saying
        quote[author] = raw_input("what author said that? \n to quit press Q \n\n")
        f['author'] = author
        if author == "Q":
            print "goodbye"
    elif saying == "Q":
        print "goodbye"


    f.close()

但它给了我一个关于“psaying = f [quote [”说“]]”

的错误

我想使用dictionnary格式将say和author结合起来，以便我可以一个接一个地搁置它们，但它让我感到困惑。

酸洗是针对单个物体的。如果要持久保存多个对象，请使用shelve模块。它将为您提供一个键值存储。

例如，您可以将enterquote更改为以下内容：

def enterquote():
    f = shelve.open('quote')
    quote = raw_input("What quote has its place in the quote book? \n to quit press Q\n\n")
    if quote != "Q":
        f['quote'] = quote
        author = raw_input("what author said that? \n to quit press Q \n\n")
        f['author'] = author
        if author == "Q":
            print "goodbye"
    elif quote == "Q":
        print "goodbye"
    f.close()

您还需要以类似的方式修改readquote功能。
