QUESTION
The code below works, copy and paste it in to run. I need some guidance though on what I need to do next. My main query here is:
I'm generating the number of TextFields with the list of questions I define. when I hit the + button, that then prints my answers to the console. What I want to be able to do is link my loggedinuser (not defined in this code, but lets just say "me" on line 23) with the unique question identifier, and the answer to the unique question identifier. I don't need to check if the answer is correct at this moment. What do I need to do create that structure?
{user, uniqueQuestionIdentifier, answer}
...ANSWER
Answered 2020-Oct-28 at 13:17basically i have changed list to Map and adding qid as key. when you are printing you will get key and value. from the key which is qid you can get the question details and from value you will have as answers.

I am new to Spring integration, trying to send an email with attachment (excel sheet) using spring integration mail dependency with DSL configuration.
My problem is I don't know how to add the attachments in Mail.outboundadapter
IntegrationFlow
. Is anyone having the attachment sample please post it or share some sample code? I have gone through the spring docs, could not understand the attachment concept there.Below is my code.

MailSendingMessageHandler
has various mapping strategies that use Spring’sMailMessage
abstraction. If the received message’s payload is already aMailMessage
instance, it is sent directly. Therefore, we generally recommend that you precede this consumer with a transformer for non-trivialMailMessage
construction requirements. However, Spring Integration supports a few simple message mapping strategies. For example, if the message payload is a byte array, that is mapped to an attachment.
The code over on the matter is like this:
QUESTION
My project has a dependency on another project, and I'm using git dependency as follows in the setup.py
file:
ANSWER
Answered 2020-Mar-09 at 18:111.
Is it best practice to include a "
pyyaml==5.1.2
" inside both projects'setup.py
,install_requires: ...
(orrequirements.txt
as you prefer) [...]?
Only applications should (possibly) pin requirements to a specific version. Libraries should restrict to a range of known compatible versions (as accurate as possible).
In general I believe pinning the versions of dependencies in setup.py
(or pyproject.toml
) is a bad idea, since those can not be (easily) overruled by the end user, the one ultimately installing the projects (doesn't matter if applications or libraries) and the one who should have the last word on what gets installed. On the other hand it is good practice to give a recommendation of a combination of pinned versions of dependencies that is known to work well (because it has been tested) in the form of a requirements.txt
file that the end user might opt to use or not (for applications, this doesn't make much sense for libraries).
Read for example Donald Stufft's article "setup.py vs requirements.txt".
2.
is it recommended to only have pyyaml listed as a dependency in the flan project, and then inherit the version in the parent project, even though it's then less clear that pyyaml is a dependency of the parent project [...]?
The general (obvious) rule is that all projects should list all of their own dependencies and only their own dependencies. Anything else doesn't make any sense (of course there might be exceptions as always).
QUESTION
I am trying to run a bash script from my Python code. I am calling the script in a subprocess like so:
...ANSWER
Answered 2019-Jul-22 at 17:01After lots of debugging, I found the issue. While the paths I listed exist if I ls
them in powershell, typing bash
in powershell doesn't just open a bash
shell, it actually changes the directory structure. I think this may be related to the Windows Subsystem for Linux, but the result is that C:
changes to /mnt/c
once inside the bash
shell. Replacing this in all my paths, I was able to run my scripts.
QUESTION
The program runs and exits with code 0, but gives no output, it's supposed to be a linear search program
I looked to other similar problems, i tried to end the array with \n. tried instead of just relying in just the "if (strcmp=0)" to make something with the values strcmp return, I'm very new and for what I'm learning not very good, just made things worst, i tried to look if it was about the char* values strcmp expect, but couldn't find the problem

Answered 2019-May-21 at 07:03You want to pass it a string to find, not just one character Also, elementos
should be a 2D array. Change the signature of your function to this:
QUESTION
I have one constraint set
after some modification I have to remove this constraint:model.addConstr(LHS10_2 <= LHS10_1)set from the model. model.remove() is not working. How can I do it? Thank for your help.
model.remove(LHS10_2 <= LHS10_1) can not work.
...ANSWER
Answered 2019-Apr-24 at 14:18The method GRBModel::addConstr() returns an GRBConstr object that you should save in a local variable. Then at a later point in time, you can use the GRBModel::remove() method to delete that particular constraint from the model again, i.e., you could do something like
QUESTION
I have been trying to create an image classifier in Python OpenCV 3.2.0 using keypoints and the bag of words technique. After some reading I found that I could peform this as follows
- Extract image descriptors using AKAZE
- Perform k-means clustering on the descriptors to generate the dictionary
- Generate histograms of images based on dictionary
- Train SVM using histograms
I managed to do steps 1 and 2 but have gotten stuck on steps 3 and 4.
I generated the histograms by using the labels returned by k-means clustering successfully (I think). However, when I wanted to use new test data that was not used to generate the dictionary I had some unexpected results. I tried to use a FLANN matcher like in this tutorial but the results I get from generating the histograms from the label data does not match the data returned from the FLANN matching.
I load up the images:

QUESTION
I am trying to 1st divide up four-letter words based upon the last two letters of the word (suffix) and 2nd count up how many words I have for each of these endings.
I have a list containing 3,164 words called filtered and I have sorted them by their suffixes, which doesn't seem much of a help.
(I want to create a dictionary that takes the suffix as a key and the words as a list but I don't know where to begin!) It would be something like:
OUTPUT:
dic = {'ab': ['Ahab', 'Arab', 'Saab, ...]; 'al': ['Aral', 'Baal', ...]}
and so on. Would that be possible?
...ANSWER
Answered 2018-Dec-19 at 21:26Assuming that suffixes are always two letters long and are case-sensitive, you can iterate through the word list and append each word to the dict of lists with the last two letters of the word as the key:
QUESTION
I am trying to build a multiplayer game that uses Python. I am using Tornado to build the client and server. Ideally, what I would like to happen are as follows:
(a) For the client to wait for user input from the command line
(b) When the client gets user input, to send the user input to the server
(c) for the server to simulate some processing(which will be the game engine) on it and send the response back to a client.

...ANSWER
Answered 2018-Jun-21 at 17:37As I can see at the moment, problem is not in stdin interaction, but your wrong way of using coroutines. Your connect_on_websocket
and communicate_with_websocket
functions are coroutines but you are using them as a plain functions and it won't work. I propose these changes.
- Make
main()
coroutine (add decorator), don't call it, remove from theClient.__init__()
. - In name=main block schedule
client.main()
invocation withtornado.ioloop.IOLoop.instance().add_callback(client.main)
. - In
main
and all your code change coroutine-functions' (with@tornado.gen.coroutine
) calls to yield, for exampleyield self.connect_on_websocket()
instead of justself.connect_on_websocket()
That should be sufficient so you can proceed your development further.
QUESTION
I'm a React novice (decent in basic javascript) and I've created a simply password generator widget and well, I cant seem to get it working like I want. I started with 2 separate widgets (1 - to make sure I could display the randomize password and 2 - to see if I could get radio buttons and simple error checking implemented), but now that I've merged them together, the password's wont display. Can someone help me figure out where I've went wrong? Any suggestions to improve the code are greatly appreciated as well (This isnt the final version, its more a proof of concept.
