How are you running this? I assume from an IDE because this should most
likely cause an error. I would recommend trying to run your python script
from the commandline which is much more likely to print an error. 

$python your_script.py

btnSearch.get_text() should be self. btnSearch.get_text()

Typically print statements are not seen in UI applications because they
are not run from command very often or the loop in charge of handling
events swallows them (which is what happens in an IDE). I would recommend
using a popup window or changing the text of a field instead. Or you can
use the python logger and just look at the log file afterwards.
