.NET/C# Interop to Python -

-

my backend written in .net/c#, have requirement need execute python scripts passing context .net side of house. these queued in background task engine called hangfire running windows service.

i did little digging , found ironpython, however, after implementing failed support many of pypi python packages need execute inside script.

secondly, looked @ python.net embedded interpreter embeds or extends cpython. cpython can run scripts/etc needed, however, found opening/closing python interpreter time can create quite few memory leaks , there threading constraints there too. see docs of details.

i'm wondering if interopt , embedding python in .net idea. i'm wondering if making python own execution engine using celery , marshalling data between 2 using protobufs better solution? adds more complexity , additional task engine stack too.

i wondering if else had ideas/feedback/experiences trying accomplishing similar? thanks!

i argue pythonnet best option:

  1. embedded python interpreter not same python sub-interpreter. sub-interpreter used less, while cpython has been embedded in major applications. memory leaks should unlikely due pythonnet taking care of you.
  2. the embedded interpreter not have shutdown between calls - in fact can expensive, can keep persistent long application alive.
  3. threading issues can avoided if enclose code requiring gil using (py.gil()) {} blocks.
  4. the added benefit of debugging cpython/.net code in mixed-mode using ptvs.

i have been playing around irb , have string looks this: irb(main):072:0> puts ["[\"4354 5432 5432 xxxxx\", \"6547 6547 8543 xxxxx\", \"2344 6543 6674 xxxxx\", \"2346 6236 7543 xxxxx\", \"1273 5585 5587 xxxxx\"]"] => nil irb(main):073:0> what want gsub last 2 "x" s of each 17 digit combination, 23 . what i've tried far (i've been using rubular): a.gsub(/\d[x]/,"23") <= grabs "x" s i'm close a.gsub(/\w[x{2}]/,"23") <= grabs "x" s grabs two digits each combination. is there easier way i'm not understanding? a.gsub(/\d{4} \d{4} \d{4} xxx\kxx/, '23') \d{4} = 4 digits what \k drop matched far. can use don't replace entire number, still able validate have in desired format.
