Cleaning up after a python script has been run locally vs from Django -

edit: when "global variables" in post, i'm referring mtcbody script; django code doesn't make use of global variables.

i have rather cryptic problem; have python script takes in xml file, parses , returns sort of result. script has global variables uses job. when run script locally, eclipse example, these global variables , else automatically destroyed @ end , new run uses new resources (as expected).

however, when run script django view, expect same behaviour instead, script persists global variables , adds them every time request made.

here's example of running locally eclipse:

import mtcbody  def doshit():     context = {}     result = mtcbody.getdata()      # variable result['tvas_after'] 1 of global variables in mtcbody script     print 'tvas after: ' + str(result['tvas_after'])      return context  if __name__ == '__main__':     doshit() 

and result after first run:

tvas after: {'1': <mtcbody.tva instance @ 0x7f28011aac20>} 

the result after second run:

tvas after: {'1': <mtcbody.tva instance @ 0x7f94bbb96c20>} 

the result after third run:

tvas after: {'1': <mtcbody.tva instance @ 0x7f9509f49c20>} 

as can see, dictionary holds tva instances repopulated scratch during each run; compare behaviour when running same script django view:

def index(request):     context = requestcontext(request)     result = mtcbody.getdata()      print 'tvas after: ' + str(result['tvas_after'])      return render(request, 'dashboardbase/table.html', context) 

result after first refresh (request)

tvas after: {'1': <multitvaconfig.mtc.mtcbody.tva instance @ 0x7ff0850fb488>} 

result after second refresh (request)

tvas after: {'1': <multitvaconfig.mtc.mtcbody.tva instance @ 0x7ff0850fb488>, '2': <multitvaconfig.mtc.mtcbody.tva instance @ 0x7ff066e4afc8>} 

result after third refresh (request)

tvas after: {'1': <multitvaconfig.mtc.mtcbody.tva instance @ 0x7ff0850fb488>, '3': <multitvaconfig.mtc.mtcbody.tva instance @ 0x7ff0a1fa4ea8>, '2': <multitvaconfig.mtc.mtcbody.tva instance @ 0x7ff066e4afc8>} 

as can see, variables in script being retained between calls django view. can please explain behaviour , if possible how avoid , make behave if run locally.

thank you

i don't know why find behaviour hard explain. script run once , quits, server application persistent, therefore should not surprising global data persistent within application.

the solution should obvious: don't use global variables. helpful, except in odd cases when do want data persist between calls. in server environment, different users can requesting resource @ different times, global variables dangerous. in case, without seeing relevant functions within mtcbody it's hard advise, seems should pass around data within module, perhaps via class.
