Too many moving pieces and consequently options to consider.

You're completely overthinking this. There's nothing different here from any other request: the form submits via GET to the results view, the view gets the search query from request.GET["q"] or wherever, does the search and passes the results to the template.

asyncio only runs one coroutine at a time and only switches at points you define, so race conditions aren't really a thing.

Personally speaking, if you drill into your head the PEP8 than most of the time syntax will come naturally i.e. like touch typing. However, most of you know multiple languages so I can imagine it get hard remembering all :)

The problem is that you have two Python versions installed: C:\Users\afsan\Anaconda3\ C:\Users\afsan\AppData\Local\Programs\Python\Python36 Given that it seems you want to use Spyder with Anaconda, please remove your second Python version (manually, if necessary). That should fix your problem.

Here, int/int will return int only that is what happening here 22/7 gives 3 and you're type casting it to float(3) which is giving 3.0 but if you will perform float/int or int/float then it will result into float so you convert any of them to float as shown following. replace float(22/7) with float(22)/7

how to make output 22//7 on python 2.7 become 3.14159 ?i try use float(22/7) but it just give me 3.0. I try use Decimal but it just give me 3, use round(x, 6) only give 3.0 just like float.

There would be perfect algorithms for your problem of course, but you could prune some processing by finding a Strongly Connected Component of your graph. There is no chance for a node of a SCC to form a cycle with a node of another SCC. So you can then run your current algorithm for different SCCs separately which cou...

I'm running an Ubuntu 16.04 VM on Google Compute Engine. I've created a static IP address <my_static_ip_address> and my firewall settings allow tcp:80-8888. I started the Jupyter server within the docker image with jupyter notebook --ip=0.0.0.0 --port=8888 --no-browser --allow-root and got this URL http://0.0.0.0:888...

You can't pause the update of the canvas without pausing the entire GUI. A simple solution would be for you to not draw to the canvas until you're ready for the update. Instead of calling canvas commands, push those commands onto a queue. When you're ready to refresh the display, iterate over the commands and run them....

I'm writing a graphics program in Python and I would like to know how to make a Canvas update only on-demand; that is, stop a canvas from updating every run of the event loop and instead update only when I tell it to. I want to do this because in my program I have a separate thread that reads graphics data from standar...

You probably don't want to provide the actual keys and other private information at all, hashed or otherwise. Besides being a security issue, it probably violates all sorts of agreements you implicitly made with the provider. Anyone using the application should be able to get their own key in the same manner you did. Y...

I would like to release the code for an application I made in Python to the public, just as a pastebin link. However, the app needs a client ID, secret and user agent to access the API (for reddit in this case). How can I store the key strings in the python code without giving everyone free reign on my api access? Mayb...

Didn't find it in the docs, but a friend who knows a bit of raw helped me out. Use for message in r.inbox.messages() (where r is an instance of reddit) to get the messages. Use message.text to get the content, and message.subject to get the title.

I'm creating a Reddit bot with praw, and I want to have the bot do things based on private messages sent to it. I searched the documentation for a bit, but couldn't find anything on reading private messages, only sending them. I want to get both the title and the content of the message. So how can I do this?

This question has been asked, but oddly enough the answers are out of date or not sufficient. I have installed anaconda, I have setup an environment running py2.7. I launch a win7 cmd prompt and type activate python27 (my custom python environment). I then import sys and then sys.path to see what my python paths are. ...

Try the 'VGAM' package. There is a function called vglm. example: vglm(Var2~factor(Var1),cumulative(parallel = F),data) generalized order model cumulative(parallel=T) will perform a proportional odds model. parallel=F is the default.

I would like to fit a generalized ordered logit model to some data I have. I first tried to use the ordered logit model using the MASS package from R, but it seems that the proportional odds assumption is violated by the data. Indeed, not all independent variables do exert the same effect across all categories of the d...

Actually in my case this was appearing due to unexpectedly something else was also getting in the data after getting pickled and before being sent to other end. So I was trying to unpickle some garbage data. Thats why this contained some unidentified character.

I am creating a tuple of two objects and pickling them. And when I try to unpickle them on the server side after passing it through sockets. It gives the above mentioned error.

There is no such thing, a bulk queries contains a list of queries to insert / update or delete documents. elasticsearch is not a database (no ACID / no transaction etc..), so you must create a rollback feature yourself.

As far as I know, they are not any Python libraries that do what the brms and rstanarm R packages do, i.e. come with precompiled Stan models that allow users to draw from the predictive distribution in the high-level language.

Very briefly, you have three sets of data: training, testing, and validation. These inputs should be distinct; any duplication between data sets will reduce some desirable aspect of your final model. Training data is used just the way you think: these are the inputs that are matched with the expected outputs (after fi...

I would like to know if the validation set influences in any way the training of the network, or if it's sole purpose is to monitor the training progress (with the tensorflow for poets project in question). If doesn't, is it okay/good-practice to reduce the validation and training sets to zero once I know the accuracy ...
Is the validation set used for anything besides monitoring progress on the Tensorflow for poets google code lab's project?

Usually, when we say "language X has first-class functions", we actually mean that "language X treats functions as first-class" (just like it does with other types). It usually means that you can pass functions as arguments, store them in arrays, etc. I don't see any reason why a particular language (that treated funct...

First, to clarify the nomenclature. The term "first class functions" means that it is "first class" in the type system: that is, that functions themselves are values. In languages where functions are not first class, functions are defined as a relationship between values, which makes them "second class". Put another wa...

If you are using cx_Freeze 5.1, there was a bug that resulted in this error. It has been corrected in the source so if you checkout the latest source and compile it yourself it should work for you. If not, let me know!

When I run my compiled program (cx_Freeze) it says __init__line 31. no module named codecs. I have Python 3.6, does anybody know why it says that, and how to maybe fix it? I have seen the other questions here on StackOverflow, but they don't seem to solve the problem for me and possibly other too. Thanks in advance!
