Communication between two python scripts

Question

a methodology question:

I have a \"main\" python script which runs on an infinite loop on my system, and I want to send information to it (a json data string for exa

Answer 1

Since the "main" script looks like a service you can enhance it with a web API. bottle is the perfect solution for this. With this additional code your python script is able to receive requests and process them:

import json

from bottle import run, post, request, response

@post('/process')
def my_process():
  req_obj = json.loads(request.body.read())
  # do something with req_obj
  # ...
  return 'All done'

run(host='localhost', port=8080, debug=True)

The client script may use the httplib to send a message to the server and read the response:

import httplib

c = httplib.HTTPConnection('localhost', 8080)
c.request('POST', '/process', '{}')
doc = c.getresponse().read()
print doc
# 'All done'
