A debugpy alternative to pdb.post_mortem() that allows you to attach any debugger to your code after an exception has been raised.
By default it is setup and tested with vscode, but feel free to contribute to add support for other debuggers.
pip install afterthoughtimport afterthought
def bombs():
a = []
print(a[0])
if __name__ == "__main__":
try:
bombs()
except Exception as e:
afterthought.debug(e)You can then connect using any tool that supports https://github.com/microsoft/debugpy
You can also use the @afterthought.debug_on_exception decorator to automatically attach the debugger to any function that raises an exception.
import afterthought
@afterthought.debug_on_exception(IndexError)
def bombs():
a = []
print(a[0])
if __name__ == "__main__":
