I am not sure how to extract multiple pages from a search result using Pythons Wikipedia plugin. Some advice would be appreciated.
My code so far:...

You have done the hard part, the results are already in the
But the results need parsing by the
wiki.page() nethod, which only takes one argument.
The solution? Use a loop to parse all results one by one.
The easiest way will be using for loops, but the list comprehension method is the best.
Replace the last two lines with the following:

Your code works, the issue why you are not able to create
res successfully is because the code does not raise just the normal
Exception class. Since the task fails it ends up calling
asyncio.exceptions.CancelledError which if we take a look in the documentation inherits from
Exception. This change is new as of Python 3.8 and since you are using Python 3.9 that change is live. Changing your code slightly to the following yields:
I'm stuck on a problem with writing a parser in Haskell that I hope someone can help out with!
It is a bit more complicated than my usual parser because there are two layers of parsing. First a language definition is parsed into an AST, then that AST is transformed into another parser that parses the actual language.
I have made pretty good progress so far but I'm stuck on implementing recursion in the language definition. As the language definition is transformed from AST into a parser in a recursive function, I can't work out how it can call itself if it doesn't exist yet.
I'm finding it a bit hard to explain my problem, so maybe an example will help.
The language definition might define that a language consists of three keywords in sequence and then optional recursion in brackets....

I believe you can use laziness here. Pass the final parser as a parameter to
transformSyntaxExprToParser, and when you see a
Recurse, return that parser.
I have the below YAML file, containing the parsing logic to match a file name:...

Here's an idea, using
pandas.eval, not sure how much it suits your case.
I am new to handling multiprocessing, multithreading etc.. in python.
I am trying to subscribe to multiple Websocket streams from my crypto exchange (API Docs Here), using
However, when I run the code below, I only receive
ticker information, but not
order book updates.
How can I fix the code to get both information?
What is the reason that only one websocket seems to be working when it's run on
(When I run the functions
ws_tickerInfo() separately, without using
multiprocessing, it works fine individually so it is not the exchange's problem.)

You have created two daemon processes. They will terminate when all non-daemon processes have terminated, which in this case is the main process, which terminates immediately after creating the daemon processes. You are lucky that even one of the processes has a chance to produce output, but why take chances? Do not use dameon processes. Instead:

You can try this:
- Add the X-Forwarded-For to the "HTTP Request Headers" (goto the API-Gateway configuration -> Resources -> Method Request).
- Add a Template with Content-Type: application/json (Resources -> Integration Request -> "Mapping Templates")
- Add a Mapping to the template

ANSWERAnswered 2021-Jun-02 at 21:22
There's no base64 here. The 'data' member is just a byte string of a gzipped file. They're stored as signed integers, so they have to be converted to unsigned for processing. I can't identify the file format after decompression, but it does have some readable strings in it.

With the goal of 'Using Python 3 to make a list of the files in a directory and store it into a indexstore variable'.
The first problem I see is that you create a class Indexstore but later completely obviate the class when you assign the variable Indexstore = .
so given you have a valid list of files from:
listOfFile = os.listdir(SourcePath)
This is an approach that will work:
First build an IndexItem class:
