Comparing list and string variables to return true

[neurowink]

I am having issues comparing a list and a string variable. In a code component, I have a script where I assess if participants clicked in one of 4 images on a screen (item_1, item_2, item_3, item_4) and see if this image matches a variable in my conditions file known as “corrAns”

#Begin experiment
item_score = 0

#End Routine
if testMouse.clicked_name == ['item_1'] and corrAns == 'item_1':
    item_score == item_score+1
elif testMouse.clicked_name == ['item_2'] and corrAns == 'item_2':
    item_score == item_score+1
elif testMouse.clicked_name == ['item_3'] and corrAns == 'item_3':
    item_score == item_score+1
elif testMouse.clicked_name == ['item_4'] and corrAns == 'item_4':
    item_score == item_score+1
else:
    item_score == item_score+0

thisExp.addData("ItemScore", item_score)

In the output “ItemScore” always ends up as 0. I tried debugging to explore what type testMouse.clicked_name and corrAns come out as. Clicked_name produces a list (e.g., [item_1, item_1]) whereas corrAns is string.

I suspect this might be the issue when I am comparing clicked_name to corrAns. Is there anyway to compare a list and string so that it can return “true” when they match?

I started looking at this previous discussion which helped me get started:

How to compare inputText to CorAns

You need to actually tell your text stimulus to display your theseKeys variable. Yes, you are responsible for that now, since there is no keyboard component trying to do it automatically. e.g. something like editing the code above: if key == 'return': # store the response in the data file: thisExp.addData('response', theseKeys) # test if it was correct: if theseKeys == corrAns: thisExp.addData('response_correct', True) else: thisExp.addData('response_c…

testMouse.clicked_name

Hi There, you might need to use testMouse.clicked_name[-1] (because I think clicked_name could be a list ?)

Thanks,

Hi Becca!

Thanks for the suggestion. I had a little play around with what you suggested (you are right - it produces a list!) and managing to get everything working. For anyone else that might have a similar problem, below is the code that worked for me in the end. Although please note I also had some mistakes “==” rather than “=” at times.

if testMouse.clicked_name[0] == 'item_1' and corrAns == 'item_1':
    item_score += 1
elif testMouse.clicked_name[0] == 'item_2' and corrAns == 'item_2':
    item_score += 1
elif testMouse.clicked_name[0] == 'item_3' and corrAns == 'item_3':
    item_score += 1
elif testMouse.clicked_name[0] == 'item_4' and corrAns == 'item_4':
    item_score += 1
else:
    item_score += 0
