Label statements allow the given name to be assigned to a program point. They exist solely to be called or jumped to, whether by script code or the Ren'Py config. ::
|
|
|
|
|
Label语句可以给脚本中的某一点命名，这个名字是唯一的，可以被脚本代码或Ren'Py调用或跳转。

A label statement may have a block associated with it. In that case, control enters the block whenever the label statement is reached, and proceeds with the statement after the label statement whenever the end of the block is reached.

|
一条label语句可能会有一个代码块与之关联，这样的话，当控制流运行这条label语句的时候便会进入代码块并执行其中的代码，直到代码块的全部被执行完毕。

The label statement may take an optional list of parameters. These parameters are processed as described in PEP 3102, with two exceptions:

If the ``expression`` keyword is present, the expression following it is evaluated, and the string so computed is used as the label name of the statement to jump to. If the ``expression`` keyword is not present, the label name of the statement to jump to must be explicitly given.
|
|
|
|
|
如果使用了``expression``关键字，那么会先运行expression后面的语句，并将运行的结果作为一个label的名称，并跳转过去。如果没有使用``expression``关键字那么必须显式地指定将要跳转的标签的名称。

Unlike call, jump does not push the next statement onto a stack. As a result, there's no way to return to where you've jumped from. ::
|
|
|
|
|
不同于call，jump不能将下个语句推至堆栈上。因此，您是没有办法返回jump出的地方的。
