请问 如何才能在except block中把在try block捕捉到的异常 打印出来(或者保存到文件中). 事先不知道异常种类

try:
    dosth()
except:
    #把异常信息打印出来, 比如这里是方法没定义

用traceback模块

first I advice you see the python manual!

second is the answer:(copy from this manual)


    import sys
    print sys.exc_info()

These details are also available through the sys.exc_info() function, which
returns a tuple (exc_type, exc_value, exc_traceback). Use of the
corresponding variables is deprecated in favor of this function, since their
use is unsafe in a threaded program.
