i need 4 more test case so i can find the bug in file scope.py Scope ACTIVITY Download the files scope .py and test_scope.py from Labo2 on Moodle. Study the code in both files. Run the test script. Observe the errors! Don't fix them yet. Add at least 4 new test cases to the test script. Re-order your tests. You'll get different reports! Copy/paste the output of your test script, showing errors to the lab02-transcript.txt file. #scope.py def find_duplicates (alist): Purpose: Return a list of duplicate values found in alist.
