错误时自动启动python调试器

您可以使用traceback.print_exc打印异常跟踪。然后使用sys.exc_info提取回溯，最后使用该回溯调用pdb.post_mortem

import pdb, traceback, sysdef bombs():    a = []    print a[0]if __name__ == '__main__':    try:        bombs()    except:        extype, value, tb = sys.exc_info()        traceback.print_exc()        pdb.post_mortem(tb)

如果您要使用产生异常的框架的局部语言使用pre.interact启动交互式命令行，则可以执行

import traceback, sys, predef bombs():    a = []    print a[0]if __name__ == '__main__':    try:        bombs()    except:        type, value, tb = sys.exc_info()        traceback.print_exc()        last_frame = lambda tb=tb: last_frame(tb.tb_next) if tb.tb_next else tb        frame = last_frame().tb_frame        ns = dict(frame.f_globals)        ns.update(frame.f_locals)        pre.interact(local=ns)
