Looking good! Only a few minor details to fix.

Also, please add some text to the commit message explaining the change; only needs to be a line or two for this (put that before the signed-off-by).

The indentation is off on the second comment line. Also, please add an example of the input (i.e., the line you're trying to parse) along with the output.

Please add a short comment explaining this (could just be, e.g., "No interesting output after this")

This should be inside the if statement.

Alternatively, you could save one level of indentation by reversing the if statement above and turning it into a "continue". I.e., replace

```
if len(line.strip()) >= 1:
   # lots of code here
```
with
```
if not line.strip():
  continue
# code here (unindented)
```

Up to you which you prefer :)
