"Looks like" is a poor indication of anything much; "feels like" is a
bit vague, but may be more useful. If you can manipulate objects and
references to objects, if you can use Python's rich object set and
standard library, if you can use Python-like features using reasonably
readable syntax, then it feels like Python. Little things don't matter
(eg whether 'print' is a keyword or a function). Big things do (eg
having to explicitly deallocate objects).

Lots of languages "look like" C. Some of them function like C (eg
C++), and most definitely "feel like" C. Others don't.
