''String'模块对象没有属性'join'

Question

所以，我想在Pygame中创建一个用户文本输入框，并告诉我看一个名为inputbox的类模块。因此，我下载了inputbox.py并导入了我的主游戏文件。然后，我在其中运行了一个函数，并收到一个错误：

Traceback (most recent call last):
File "C:\Users\Dennis\Tournament\inputbox.py", line 64, in <module>
if __name__ == '__main__': main()
 File "C:\Users\Dennis\Tournament\inputbox.py", line 62, in main
print(ask(screen, "Name") + " was entered")
 File "C:\Users\Dennis\Tournament\inputbox.py", line 46, in ask
display_box(screen, question + ": " + string.join(current_string,""))
AttributeError: 'module' object has no attribute 'join'

我尝试独自运行inputbox.py并收到相同的错误。我正在使用Python 3.3和Pygame 3.3，所以可能是一个问题。有人告诉我最近删除了许多“字符串”函数。如果有人知道问题所在并可以解决，则代码如下：如果有人能够解决问题，我将不胜感激，因为我一直在尝试在我的Pygame游戏中设置用户输入。非常感谢您提前提供答案。

Answer 1

当您应该从str对象中使用它时，您正在尝试从字符串模块中使用join方法。

string.join(current_string,"")

例如该行应为

"".join(current_string)

其中current_string是可迭代的。

只是有关.join方法如何工作的简单示例

", ".join(['a','b','c'])

将为您提供字母a b和c的str对象，并用逗号和空格分隔。

[string.join(words[, sep]) has been deprecated with Python 2.4，已用Python 2.4完全删除

直到Python 3.0，一个人都可以同时使用Python 2.7和string.join(words[, sep])（尽管自sep.join(words)起不建议使用第一个，而从Python 2.4起只有后者可用。
