SyntaxError: invalid syntax

I'm running `missing_colon.py` as follows:

```python
division(23, 0)
```

but I get the following error:

```
  File "/Users/fuchur/Documents/24/git_sync/swe-agent-test-repo/tests/./missing_colon.py", line 4
    def division(a: float, b: float) -> float
                                             ^
SyntaxError: invalid syntax
```
