Question

Suppose I’m writing a function in python, this function can either be success or raise exception.

So which one shall I use:

1. return
2. return True
3. no return

---

Edit:

Thanks for response. In this case I mean to ask if return Value have no further meaning, shall I still do a return True or something.

The case I’m working on is to write thrift server-side function, where I hesitated whether to use void or boolean type in the service api.

Answer 1

Looks like no return is needed. From your description, the invocation could look like:

try:
    myfunc()
except MyException:
    ...
else:
    ...

No need to analyze the return value.
