测试代码

# test_raise.py
class test_context:
    def __enter__(self):
        print("enter")

    def __exit__(self, exc_type, exc_val, exc_tb):
        print("exit")


with test_context():
    print("in test_context1")
    raise ValueError("error!")
    print("in test_context2")

运行结果

root@pve828qzz5mf6x:~/test# /usr/bin/python3.8 /root/vemu_v_link_check/test_raise.py
enter
in test_context1
exit
Traceback (most recent call last):
  File "/root/test/test_raise.py", line 14, in <module>
    raise ValueError("error!")
ValueError: error!

结论

会执行

扩展

python with语句里有return， exit还会执行吗

该扩展的结论：会执行，且是在return语句执行之后。
