Answer 1

如果使用IPython，则可以使用

IPython 6.2.1   An enhanced Interactive Python. Type '?' for help.

In [1]: %pdb
Automatic pdb calling has been turned ON

In [2]: %pdb
Automatic pdb calling has been turned OFF

In [3]: ?pdb
Docstring:
Control the automatic calling of the pdb interactive debugger.

Call as '%pdb on', '%pdb 1', '%pdb off' or '%pdb 0'. If called without
argument it works as a toggle.

When an exception is triggered, IPython can optionally call the
interactive pdb debugger after the traceback printout. %pdb toggles
this feature on and off.

The initial state of this feature is set in your configuration
file (the option is ``InteractiveShell.pdb``).

If you want to just activate the debugger AFTER an exception has fired,
without having to type '%pdb on' and rerunning your code, you can use
the %debug magic.
File:      ~/anaconda/envs/py36/lib/python3.6/site-packages/IPython/core/magics/execution.py

您可能需要使用pip或conda安装IPython。在

没有一个名为pdb的命令，但是您可以使用以下命令从shell调用pdb：

python -m pdb your_script.py

您可以阅读更多方法来调用its doc中的pdb。在
