Stop PyCharm If Error

In PyCharm debugging mode, is there way to let it stop right after it hits an error but not exit and highlight the offending line? The analogous feature I have in mind is "dbstop if error" of Matlab.

The given answer was confusing to me. To do this you do not need to go to preferences, what you need to go is to break points menu bar (which is not in preferences for some reason). So:

  1. Go to break point by pressing Command + shift + fn + F8 (Ctrl + Shift + F8 on Windows) or go to the breakpoints you have at the bottom (see picture 1). This opens the break point menu (see picture 2).

  2. Then click enabled (for me suspend was already on so I only needed to click enabled). That's it.

Note: the reason this feature is useful is because after running an execution it halts with exactly the program state it caused it to err. For me I have stochastic code due to machine learning and reproducing the error exactly is annoying. I'd rather just see what cased the error, inspect the program state, stack etc and just fix it. There is even a little window at the bottom right to run code so I can test it right there while I am fixing it. I can even do control+shift+E to test pieces of code from my actual code (as I right new code).

Yes, there is. Under Run, if you hit View Breakpoints (Ctrl + Shift + F8 on Windows) there's a checkbox where you can create an exception breakpoint for any exception.enter image description here
