Suggestions for Python debugging tools? [closed]

问题

Yesterday I made a simulation using Python. I had a few difficulties with variables and debugging.

Is there any software for Python, which provides a decent debugger?

Don't forget about post-mortem debugging! After an exception is thrown, the stack frame with all of the locals is contained within sys.last_traceback. You can do pdb.pm() to go to the stack frame where the exception was thrown then p(retty)p(rint) the locals().

Here is a function that uses this information to extract the local variables from the stack.

def findlocals(search, startframe=None, trace=False):      from pprint import pprint     import inspect, pdb      startframe = startframe or sys.last_traceback     frames = inspect.getinnerframes(startframe)      frame = [tb for (tb, _, lineno, fname, _, _) in frames              if search in (lineno, fname)][0]      if trace:         pprint(frame.f_locals)         pdb.set_trace(frame)     return frame.f_locals

Usage:

>>> def screwyFunc():     a = 0     return 2/a  >>> screwyFunc()  Traceback (most recent call last):   File "<pyshell#62>", line 1, in <module>     screwyFunc()   File "<pyshell#55>", line 3, in screwyFunc     return 2/a ZeroDivisionError: integer division or modulo by zero >>> findlocals('screwyFunc') {'a': 0}

Winpdb is a platform independent graphical GPL Python debugger with support for remote debugging over a network, multiple threads, namespace modification, embedded debugging, encrypted communication and is up to 20 times faster than pdb.

Features:

GPL license. Winpdb is Free Software.
Compatible with CPython 2.3 through 2.6 and Python 3000
Compatible with wxPython 2.6 through 2.8
Platform independent, and tested on Ubuntu Gutsy and Windows XP.
User Interfaces: rpdb2 is console based, while winpdb requires wxPython 2.6 or later.

pudb is a visual debugger for python.

回答4:

You can check out the python debugger pdb, which is included in the standard library: http://docs.python.org/library/pdb.html

回答5:

As the post suggested, there are a few options:

pdb: Python's built-in debugger
pudb: GUI debugger
pydbgr: a rewrite of the pydb debugger
ipdb: iPython's ipdb

回答6:

I'd recommend pydb and ipython for interactive debugging.

Both have screencasts available at showmedo.com

Komodo IDE (not the free Komodo Edit) comes with a debugger. I haven't used it in over a year, but it was good back then (v 3, IIRC).

回答8:

There is an Eclipse plug-in for Python which supports debugging, among other tools. See the The Tutorial to start with, and the Website for download. Off course you will need to get Eclipse as well.

回答9:

I used PyCharm and WingIDE for debugging, both are great.

PyCharm uses quite some RAM (it's in Java), still, I ended up using it as I can debug doctests that I'm executing from it.

WindIDE is written in Python, I like it more than PyCharm except for the lack of running doctests.

You can also try Spyder, which I never succeeded to make work.
