中断try-except块

Question

我有一个嵌套的try-except finally块，我在其中连续运行几个函数(假设前面的函数可以工作)。我有一个条件，我在开始时检查(本质上是检查函数是否已经在当天运行)，如果这条语句是假的，我想直接跳到最后。

我可以通过强制错误发生来做到这一点(即写入x=1/0，但似乎应该有更好的方法来做到这一点)。

我的代码如下所示：

error = False
conditions = False

try:
    # Do stuff here
    if not condition:
        # Here I want to go directly to finally
except Exception:
    error = True
else:
    try:
        # Do stuff here
    except Exception:
        error = True
    else:
        try:
            # Do stuff here
        except Exception:
            error = True
finally:
    if error:
        # Report that an error occurred
    else:
        # Report that everything went well

这个怎么样？

为了在对这个答案的评论中使用MisterMiyagi的出色措辞，它颠倒了逻辑，只有在满足条件时才继续。

error = False
conditions = False

try:
    # Do stuff here
except Exception:
    error = True
else:
    if condition:  # The inverted condition moved here.
        try:
            # Do stuff here
        except Exception:
            error = True
        else:
            try:
                # Do stuff here
            except Exception:
                error = True
finally:
    if error:
        # Report that an error occurred
    else:
        # Report that everything went well
