停在变量被改变的那一行 [英] Stop at the line where a variable gets changed

问题描述

我正在尝试追踪变量何时更新.我有一个观察者，但有什么方法可以设置它，以便在值更新时暂停执行?

I am trying to track down when a variable gets updated. I have a watcher, but is there any way to set it up so that the execution can be paused when the value is getting updated?

这称为观察点或数据断点.

推荐答案

目前pycharm没有实时跟踪变量修改的默认内置功能.或者，您可以这样做:

Currently pycharm does not have a default built-in feature that tracks variable modification in real time. Alternatively you can do this:

1. 运行调试
2. 在调试器窗格 -> 变量中，右键单击要跟踪的变量并将其添加到 Watches.
3. 在 Watches 窗格中，右键单击变量并选择引用对象.

我相信您所说的功能称为观察点支持，根据这篇文章:http://sourceforge.net/blog/watchpoints-in-python/Eric 和 PyScriptor 有这个功能，但 pycharm 没有.

The feature you are talking about is, I believe, called watchpoint support and according to this article: http://sourceforge.net/blog/watchpoints-in-python/ Eric and PyScriptor has the feature but not pycharm.
