These results might also be of interest:

>>> def res():
...   try:
...    return 1
...   finally:
...    return 2
...
>>> res()
2
>>> def res():
...   try:
...    return 1
...   finally:
...    return
...
>>> res()
>>> def res():
...   try:
...    return 1
...   finally:
...    pass
...
>>> res()
1
