对Python调试工具有何建议？

对Python调试工具有何建议？

不要忘记事后调试！引发异常后，所有本地变量的堆栈框架都包含在中

sys.last_traceback

。您可以

pdb.pm()

转到引发异常的堆栈帧，然后p（retty）p（rint）the

locals()

。

这是一个使用此信息从堆栈中提取局部变量的函数。

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

用法：

>>> 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/aZeroDivisionError: integer division or modulo by zero>>> findlocals('screwyFunc'){'a': 0}
