Question

try：dosometingexcept：os._exit(0)比如执行dosometing时有错误，我想再试两次，如果两次执行还是有错误，那就os._exit(0)退出

Answer 1

我找到方法了，分享出来importos
attempts=0
success=False
whileattempts<3andnotsuccess:
try:
	dosomething
	success=True
except:
	attempts+=1
	ifattempts==3:
	os._exit(0)
                            

Answer 2

呃，这样？defretry_do(func,retry=None):
try：
func()
except：
ifretry:
retry()
else:
os._exit(0)
defdo_sth():
#dosomething
retry_do(do_sth,retry_do(do_sth,retry_do(do_sth)))
