what you try to do will never work because your attempts are at using
python on the client side and only javascript works for that purpose.
But for this popup thing javascript is just fine so if all you want to
do is this then you don't need python at the first place.

how can i convert a string like "10, 20, 30" to a list [10, 20, 30]
what i can do is:

if you want the numbers you can combine it into one-liner
nums = file(r"C:\folder\myFile.txt").read().split(";")
the numbers are in string representation in the list
you can no do
nums = [float(num) for num in nums]

here you could read all as string and split it on "New"
here small example
>>> txt = "fooXbarXfoobar"
>>> txt.split("X")
['foo', 'bar', 'foobar']
>>>
in more complicated case I would use regexp but
I doubt this is neccessary in your case

I think is not very consistent
notice q.bar is bounded although type(q.bar)
says it's types.UnboundedMethodType
what do you think?

the same id-value would enforce two objects to be
of the same type (trivial case)
the reverse is not necessarily true
Is it possible to pass a python object to a python program as argument?
In my program I would like to start executing an other python program
and don't wait until that finishes, only launch it and keep running
the original program. The obvious way I can think of it is using the
exec* or spawn* fun

Okay, but how? It seems to me that if the process which issued
