Python replace 错误 (AttributeError: 'tuple' 对象没有 'replace' 属性)

Question

环境

我正在使用Python 3，操作系统是Windows 7。我知道从Python 2.7升级到3的时候，有些命令发生了变化（我之前用的是2.7）。

问题

这个变量是临时的，但它是这样的：

(((((0, 7), 7), 8), 4), 5) 

下面是用来去掉括号的代码：

randy = randy.replace(")", "")
randy = randy.replace("(", "")
randy = randy.replace(" ", "")

当我尝试执行替换函数时，出现了一个错误：

Traceback (most recent call last):
File "<string>", line 248, in run_nodebug
File "Criptic.py", line 134, in <module>
randy = randy.replace(")", "")
AttributeError: 'tuple' object has no attribute 'replace'

编辑：

Answer 1

exam_st_date = (11, 12, 2014)
# Sample Output : The examination will start from : 11 / 12 / 2014

newtup = str(exam_st_date).replace(',', ' /')


print(newtup)

看看我的例子，应该能给你一些结果。

Answer 2

randy = randy,rand

这个写法创建了一个包含两个元素的元组，元组是没有叫做 replace 的方法的。

如果你只是想把数字用逗号分隔开，放到一个列表里，你可以在你的循环中这样做：

randy = []
num = 0
while num < finalcount:
    rand = random.randrange(1,9)
    randy.append(rand)

然后你可以去掉 replace 的那几行，改成这样做

randy = ",".join(randy)

这样就能得到一个用逗号分隔的字符串了。

你可能应该在你的问题中加上你想要得到的输出，因为现在看起来不太清楚你到底想做什么。

Answer 3

你有一个包含数字的元组（可以理解为一种列表），你想把它变成一个字符串。这里的括号不能被替换掉，因为它们不是变量的一部分，只是用来表示这个元组的。

你应该使用 join() 和 str() 来实现这个转换。

 result = " ".join(str(x) for x in randy)

不过，这样做可能也不会得到正确的结果，因为它是一个嵌套的元组列表。你可能想要的是：randy = randy + (rand,)，而不是 randy = randy,rand。
