从python中运行python脚本并捕获异常

Question

从python中运行python脚本并捕获异常。

File: test1.py

try:
    a = 1/0
except:
    raise

File: test2.py

import subprocess
subprocess.call('python test.py', shell=True)

如何运行test1.py并捕获test2.py中的ZeroDivisionError？

Answer 1

您可以使用exec：

来实现这一目标

with open('script.py') as f:
    script = f.read()
    try:
        exec(script)
    except ZeroDivisionError as e:
        print('yay!', e)

Answer 2

您使用子进程有特殊原因吗？ 我会这样做的

test1.py

def test
    try:
        a = 1/0
    except:
        raise

test2.py

import test1

try:
    test1.test()
except
    whateveryouwannado

Answer 3

使用try except并使用function来电会更好，

test1.py

def solve():
    try:
        a = 1/0
    except ZeroDivisionError as e:
        print e.message
solve()

test2.py

import subprocess
subprocess.call('python foo.py', shell=True)
