hi all, i would like to take keyboard number presses and display them on the screen. participants can press any number between 1-100, then press enter to move to the next trial. i can only get it to display the previous number (theseKeys[-1]) or all the numbers (theseKeys) in the form [‘8’ ‘5’ ‘retu…

The following might work: theseKeys3 = event.getKeys(keyList=['1','2','3','4','5','6','7','8','9','0', 'return']) key_resp_3.keys.extend([key for key in theseKeys3 if key != "return"]) choicetext.setText("".join(key_resp_3.keys)) if "return" in theseKeys3: continueRoutine=False

thank you so much- that worked. if you have a moment could you explain this part: [key for key in theseKeys3 if key != “return”] I am trying to save the number as an integer for my record and also for use in the next trial. I’ve tested it with print key_resp_3.keys / key / theseKeys3 / join(key_re…

Hi Laurel, Sure. That is a ‘list comprehension’, and is a short way of doing the following: keys = [] for key in theseKeys3: if key != "return": keys.append(key) If you want to save it as an integer, you need to convert the list of strings contained in key_resp_3.keys: # convert the …

thank you so much djmannion, that works perfectly. I have now added a backspace to the task too, to let the participant delete mistakes (in case anyone watching out there needs to do this too). Laurel theseKeys3 = event.getKeys(keyList=['1','2','3','4','5','6','7','8','9','0', 'return…

Hi, What is "key_resp_3’ here? I am trying to use coder doing similar things here. But I don’t know how to initialize ‘key_resp_3’. I tried both empty dictionary and key_resp_3 = event.BuilderKeyResponse(). Nether of them works.

Thank you for your reply. I went through all the relative links and came up with several lines in the code component in the builder. Want I want to do in a single trial is that show an image to participant and display their response on the next display, and their response will be only numbers betwee…

@Miao, you can either create a keyboard object, or use the events module. If you want to use the event module, see Writen response for an idea of what to do.
