I am working on a spatial search case for spheres in which I want to find connected spheres. For this aim, I searched around each sphere for spheres that centers are in a (maximum sphere diameter) distance from the searching sphere’s center. At first, I tried to use scipy related methods to do so, but scipy method takes longer times comparing to equivalent numpy method. For scipy, I have determined the number of K-nearest spheres firstly and then find them by cKDTree.query, which lead to more time consumption. However, it is slower than numpy method even by omitting the first step with a constant value (it is not good to omit the first step in this case). It is contrary to my expectations about scipy spatial searching speed. So, I tried to use some list-loops instead some numpy lines for speeding up using numba prange. Numba run the code a little faster, but I believe that this code can be optimized for better performances, perhaps by vectorization, using other alternative numpy modules or using numba in another way. I have used iteration on all spheres due to prevent probable memory leaks and …, where number of spheres are high.

While creating datasets for matching and extracting IDs and SubIDs with their names I have the following code in HTML after getting the file from requests module -

I am trying to use Selenium in Google Colab, but i get some errors when i try to run a Firefox instance. i followed this links:

• Selenium documentation here, i tried with the Driver Management Software but i got the error that says that was unable to find the binary location to Firefox, so i follow this other link , but i was unable to make it run

So i tried with the Hard Coded Location, but I got the error:

Yes I know there are a number of questions (e.g. (0) or (1)) which seem to ask the same, but AFAICS none really answers what I want.

What I want is, to replace any occurrence of a newline (LF) with the string \n, with no implicitly assumed newlines... and this with POSIX only utilities (and no GNU extensions or Bashisms) and input read from stdin with no buffering of that is desired.

So for example:

• printf 'foo' | magic should give foo
• printf 'foo\n' | magic should give foo\n
• printf 'foo\n\n' | magic should give foo\n\n

The usually given answers, don't do this, e.g.:

• awk
  printf 'foo' | awk 1 ORS='\\n gives foo\n, whereas it should give just foo
  so adds an \n when there was no newline.
• sed
  would work for just foo but in all other cases, like:
  printf 'foo\n' | sed ':a;N;$!ba;s/\n/\\n/g' gives foo, whereas it should give foo\n
  misses one final newline.
  Since I do not want any sort of buffering, I cannot just look whether the input ended in an newline and then add the missing one manually.
  And anyway... it would use GNU extensions.
  sed -z 's/\n/\\n/g'
  does work (even retains the NULs correctly), but again, GNU extension.
• tr
  can only replace with one character, whereas I need two.

The only working solution I'd have so far is with perl:
perl -p -e 's/\n/\\n/'
which works just as desired in all cases, but as I've said, I'd like to have a solution for environments where just the basic POSIX utilities are there (so no Perl or using any GNU extensions).

Thanks in advance.

I'm currently building PoC Apache Beam pipeline in GCP Dataflow. In this case, I want to create streaming pipeline with main input from PubSub and side input from BigQuery and store processed data back to BigQuery.

I am new to Python. Questions below:

1. I have a list of urls I want to scrape data from. I don't know what is wrong with my code, I am unable to retrieve results from all urls. The code is only scraping the first url and not the rest. How can I successfully scrape data (title, info, description, application) in all urls in the list?

2. If question 1 works, how can I convert the data into a CSV file?

Here is the code:

Using pure javascript, I am trying to create a price-validating function that when used, validates prices entered into a form. There are 4 requirements to my validation:

1. Input must be a number and cannot be empty
2. If a decimal is entered, there must at least be 1 pre- and post-decimal character
3. Price entered must be a number that is between $1 and $99.99 (both inclusive)
4. Price entered must not have whitespaces in between

and here is my code:

This was part of another question (Reading URLs from .csv and appending scrape results below previous with Python, BeautifulSoup, Pandas ) which was generously answered by @HedgeHog and contributed to by @QHarr. Now posting this part as a separate question.

In the code below, I'm pasting 3 example source URLs into the code and it works. But I have a long list of URLs (1000+) to scrape and they are stored in a single first column of a .csv file (let's call it 'urls.csv'). I would prefer to read directly from that file.

I think I know the basic structure of 'with open' (e.g. the way @bguest answered it below), but I'm having problems how to link that to the rest of the code, so that the rest continues to work. How can I replace the list of URLs with iterative reading of .csv, so that I'm passing the URLs correctly into the code?
