this runs fine on my local machine, but as soon as I deploy it the service fails saying invalid syntax "for"

  data = {k: request.form[k] for k in request.form.iterkeys()}   
SyntaxError: invalid syntax

Appreciate the help on this, it's been a very long time since I did anything with Python and this one has got me stumped.

  • what versions of Python are you running locally and for the service? Commented Jan 21, 2014 at 22:29

    upgrade to python 2.7 Commented Jan 21, 2014 at 22:29

    The syntax requires Python 2.7 or newer. Does your server run 2.6 perhaps? Commented Jan 21, 2014 at 22:29

As others have mentioned, this is probably a version issue. Try:

data = dict((k,request.form[k]) for k in request.form.iterkeys())

The python version on your local machine might be different from the version you have on the server.

I will check that now.
ah yes, i'm running 2.7 server is running 2.6 - Will see if I can't get that changed. Then try again.

Dict comprehensions are a relatively new addition to 2.x. Convert it to a genex that generates (key, value) pairs and pass it to the dict() constructor.

Could provide an example. Not trying to be cheeky, just not familiar with Python.
@SimonH: I linked you to a post with an example in the comments on your question.
