Python: are there ways to detect missing () in method call?

Question

I want to call a method `f()`, but accidentally I just say `f`. Python3 mistakes this for a meaningless evaluation of a nonexisting variable, and therefore skips over my intended method call without any notice. Is there a way to override this default behavior and to get an error message? Either by forbidding dual use of an identifier as a method and as a variable, or by forbidding a meaningless statement consisting just of an identifier?

Accepted Answer

It's valid syntax, so Python won't complain. You may want to consider some other tools, like pylint. Pylint would've reported:

```
W:  4,0: Statement seems to have no effect
```

If you simply did:

```
f
```

instead of:

```
f()
```

The only catch is the pylint can complain an awful lot out of the box. Make sure to create a config that is tolerant of your style.
