#Python# 如何在异常中打印异常的调用堆栈

#Python# 如何在异常中打印异常的调用堆栈

使用 traceback 库

import traceback

try:
	pass #要捕获异常的代码块
except Exception as a:
  	print(a)
  	traceback.print_exc()

或者使用 cgitb

def func(a, b):
        return a / b
if __name__ == '__main__':
        import cgitb
        cgitb.enable(format='text')
        import sys
        import traceback
        func(1, 0)
运行之后就会得到详细的数据:

A problem occurred in a Python script.  Here is the sequence of
function calls leading up to the error, in the order they occurred.

 /Users/samchi/Documents/workspace/tracebacktest/teststacktrace.py in <module>()
    4 	import cgitb
    5 	cgitb.enable(format='text')
    6 	import sys
    7 	import traceback
    8 	func(1, 0)
func = <function func>

 /Users/samchi/Documents/workspace/tracebacktest/teststacktrace.py in func(a=1, b=0)
    2 	return a / b
    3 if __name__ == '__main__':
    4 	import cgitb
    5 	cgitb.enable(format='text')
    6 	import sys
a = 1
b = 0
