I want to create an experiment in PsychoPy Builder that conditionally shows a second routine to participants based on their keyboard response.
In the task, I have a loop that first goes through a routine where participants have three options to respond ('left','right','down') and only if they select 'left', regardless of the correct answer, should they see a second routine that asks a follow-up question to respond to. The loop should then restart with routine 1 each time.
I've tried using bits of code in the "begin experiment" section as such:
if response.key=='left':
continueRoutine=True
elif response.key!='left':
continueRoutine=False
But here I get an error saying response.key is not defined.
Assuming your keyboard component is actually called response, the attribute you are looking for is called response.keys. It is pluralised as it returns a list rather than a single value. This is because it is capable of storing multiple keypresses. Even if you only specify a single response, it will still be returned as a list containing just that single response (e.g. ['left'] rather than 'left'). So you either need to extract just one element from that list (e.g. response.keys[0]) and test against that, or use a construction like if 'left' in response.keys to check inside the list.
Secondly, you don't need to have a check that assigns True to continueRoutine, as it defaults to being True at the beginning of a routine. So it is only setting it to False that results in any action. So you could simply do something like this:
if not 'left' in response.keys:
continueRoutine = False
Lastly, for PsychoPy-specific questions, you might get better support via the dedicated forum at https://discourse.psychopy.org as it allows for more to-and-fro discussion than the single question/answer structure here at SO.

From a soap XML response I need to get all the occurrences of an id (This part already done using Match No being set to -1 in Regex extractor).
And then I need to send these ids to a subsequent request. That is, the request needs to be fired as many times as of the total number of occurrences of the id, we can call it as ID_matchNr. (This is the total occurrences I got from the Regex extractor).
I used a while loop and a counter. The while loop works until the ID_matchNr, but it doesn't stop there, that while loop is infinite. How to fix this?
My counter's reference name is count and the field name in my request is ${__V(ID_${count})}. And while loop's condition is ${count}<=${ID_matchNr}. I also tried using a beanshell to save the ID_matchNr to another variable and then use it in while condition instead of directly using ID_matchNr. Still running infinitely.
Have you considered using ForEach Controller?
Given you have JMeter Variables in form of:
ID_1=foo
ID_2=bar
ID_3=baz
ID_matchNr=3
Add ForEach Controller to your Test Plan and configure it like:
And put the "subsequent" sampler as a child of the ForEach Controller and refer the generated subsequent ID value as ${CURRENT_ID} where required

Actually i want to read emails one by one in junk folder of "outlook:live" and mark emails "Not spam".
emails = WebDriverWait(driver, 5).until(EC.element_to_be_clickable((By.XPATH,"//div[#class = 'xoCOIP8PzdTVy0T6q_uG6']")))
This xpath matches 400 instances. I want to make a loop to select one email at a time like select first email, click on the div and perform action and then 2nd email and so on. I'm trying this
emails = WebDriverWait(driver,
5).until(EC.element_to_be_clickable((By.XPATH,"//div[#class =
'xoCOIP8PzdTVy0T6q_uG6']")))
for count in range(0,len(emails)):
(emails)[count+1].click()
Please help me know where im doing wrong. Thanks in advance
It appears that the function you're using to return the clickable elements is only returning a single element, so you'll have to use a different function, make a change in your logic, etc.
For instance, you could use Selenium's find_elements_by_xpath("//div[#class = 'xoCOIP8PzdTVy0T6q_uG6']") which will return a list of WebElement object(s) if the element(s) are found, or an empty list if the element(s) is not found. This will, of course, not take into consideration the possibility of the elements not being completely loaded on the page. In my experience, just slapping a time.sleep(10) after you open the page is "'good enough".
I recommend making sure your elements can be discovered and interacted with first to make sure this isn't all in vain, if you haven't already.
Another option is to add another function, something like a elements_to_be_clickable() function, to the Expected Conditions source code.
From the Expected Condition documentation, I've done some research and it looks like the element_to_be_clickable() function only returns a single element. Moreover, from the source code, said function mainly makes use of the visibility_of_element_located() function. I believe you could follow similar logic to the element_to_be_clickable() function, but instead use the visibility_of_all_elements_located() function, in order to return multiple WebElements (since visibiilty_of_all_elements_located() returns a list of WebElements).
I have an array with a few items in it. Every x seconds, I receive a new array with the latest data. I check if the data has changed, and if it has, I replace the old one with the new one:
if (currentList != responseFromHttpCall) {
currentList = responseFromHttpCall;
}
This messes up the classes provided by ng-animate, as it acts like I replaced all of the items -- well, I do actually, but I don't know how to not.
These changes can occur in the list:
There's one (or more) new item(s) in the list - not necessaryly at the end of the list though.
One (or more) items in the list might be gone (deleted).
One (or more) items might be changed.
Two (or more) items might have been swapped.
Can anyone help me in getting ng-animate to understand what classes to show? I made a small "illustation" of my problem, found here: http://plnkr.co/edit/TS401ra58dgJS18ydsG1?p=preview
Thanks a lot!
To achieve what you want, you will need to modify existing list on controller (vm.list) on every action. I have one solution that may work for your particular example.
you would need to compare 2 lists (loop through first) similar to:
vm.list.forEach((val, index)=>{
// some code to check against array that's coming from ajax call
});
in case of adding you would need to loop against other list (in your case newList):
newList.forEach((val, index)=>{
// some code to check array on controller
});
I'm not saying this is the best solution but it works and will work in your case. Keep in mind - to properly test you will need to click reset after each action since you are looking at same global original list which will persist same data throughout the app cycle since we don't change it - if you want to change it just add before end of each function:
original = angular.copy(vm.list);
You could also make this more generic and put everything on one function, but for example, here's plnkr:

Hope it helps.
I'm trying to evaluate Apache Flink for the use case we're currently running in production using custom code.
So let's say there's a stream of events each containing a specific attribute X which is a continuously increasing integer. That is a bunch of contiguous events have this attributes set to N, then the next batch has it set to N+1 etc.
I want to break the stream into windows of events with the same value of X and then do some computations on each separately.
So I define a GlobalWindow and a custom Trigger where in onElement method I check the attribute of any given element against the saved value of the current X (from state variable) and if they differ I conclude that we've accumulated all the events with X=CURRENT and it's time to do computation and increase the X value in the state.
The problem with this approach is that the element from the next logical batch (with X=CURRENT+1) has been already consumed but it's not a part of the previous batch.
Is there a way to put it back somehow into the stream so that it is properly accounted for the next batch?
Or maybe my approach is entirely wrong and there's an easier way to achieve what I need?
Thank you.
I think you are on a right track.
Trigger specifies when a window can be processed and results for a window can be emitted.
The WindowAssigner is the part which says to which window element will be assigned. So I would say you also need to provide a custom implementation of WindowAssigner that will assign same window to all elements with equal value of X.
A more idiomatic way to do this with Flink would be to use stream.keyBy(X).window(...). The keyBy(X) takes care of grouping elements by their particular value for X. You then apply any sort of window you like. In your case a SessionWindow may be a good choice. It will fire for each key after that key hasn't been seen for some configurable period of time.
This approach will be much more robust with regard to unordered data which you must always assume in a stream processing system.
I just have this question around the Stax XMLStreamWriter. Best explained by example:
Say I need to produce a document somehow like this:
<buddies>
<buddies name="tim"/>
<buddies name="toady"/>
</buddies>
, where the tim and toady guys are created by some callback that receives the XMLStreamWriter as an argument.
writer.writeElement("buddies");
callback1.writeBuddies(writer);
callback2.writeBuddies(writer);
write.writeEndElement();
Now the thing is, the whole document must conform to a schema that states: If there's a <buddies> element, there must be at least one <buddy> inside, so if none of my callbacks write anything on the stream I'd have an empty element which is invalid. Question is: Can I delay the writeElement("buddies") somehow like this:
// Pseudocode
Mark mark = writer.getPos()
boolean written = callback1.writeBuddies(writer)
written |= callback2.writeBuddies(writer)
if (written){
writer.writeStartElement(mark, "buddies") // write at mark
writer.writeStopElement() // write at the end of stream
}
Or am I completely off the track?
StAX is a forward only streaming API. To achieve what you are asking is a potential requirement for DOM parser where you construct the node "buddies" separately and attach it to the main document if it is not empty.
