I've recently moved from Matlab to Python. Python is a much better language (from the point of view of a computer scientist), but Python IDEs all seem to lack one important thing:
A proper interactive debugger.
I'm looking for:
The ability to set breakpoints graphically by clicking next to a line of code in the editor.
The ability to run ANY CODE while stopped in the debugger, including calling functions from my code, showing new windows, playing audio, etc.
When an error occurs, the debugger should automatically open an interactive console at the error line.
Once done with the interactive console, you can resume normal execution.
Matlab has all these features and they work incredibly well, but I can't find them anywhere in Python tools.
I've tried:
PyCharm: the interactive console is clunky, often fails to appear, and crashes all the time (I've tried several different versions and OSs).
IPython: can't set breakpoints -Launching a Python console programatically: you have to stop your code, insert an extra line of code, and run again from the beginning to do this. Plus, you can't access functions already imported without re-importing them.
Being able to debug and fix problems THE FIRST TIME THEY APPEAR is very important to me, as I work in programs that often take dozens of minutes to re-run (computational neuroscience).
CONCLUSION: there is NO way to do all of these in Python at the moment. Let us hope that PyLab development accelerates.
You can do all this in the iPython Notebook. Use the magic command %pdb to stop on error.
