How to fix PyException error in Sikulix 1.1.1? - sikuli

Question

I am facing the below error in my sikuli script
+++ running this Java
java version "1.7.0_21"
Java(TM) SE Runtime Environment (build 1.7.0_21-b11)

Exception: **org.python.core.PyException thrown from the UncaughtExceptionHandler
in thread "Thread-13"**
Checked and found the code is getting stuck at a line where I used image as a dictionary element
for i in menubar:
exists(menubar[i]).highlight(3)
menubar is a python dictionary which contains images which are stored with their name as key.
PS : code
from sikuli import *
menubar={"file":"menubar_file.png","edit":"menubar_edit.png","view":"menubar_view.png","administration":"menubar_administration.png","tools":"menubar_tools.png","help":"menubar_help.png"}
for i in menubar:
assert exists(menubar[i]).highlight(2)

Answer 1

The assert statement is testing a boolean expression that evaluates to True or False. The Sikuli exists() function however returns a Match object if a pattern found or None in the pattern was not found. You need to rewrite your code accordingly.
Also, I wouldn't use the highlight() like this as it is not clear what it is highlighting.
