hi all,
I'm investigating the possibilities to replace MatLab with Python
(+NumPy +SciPy).
I'm a very newbie, I just typed my first characters and calculated the
sum of 2 and 3 in Python.
My application is a Delphi program, for data-acquisition and real-time
data analysis. The real-time analysis is done with MatLab, embedded
through a OLE coupling. I already found PythonforDelphi which probably
helps a lot to make the first steps.
But I'm now stumbled about something very basic, which I don't
understand. The problem might be due to the IDE I use (PyScripter), but
I tried several and they all behave the same. And I expect that the
observed behaviour might be very important notch in my final
application (blockwise, real time interaction).
In MatLab I declare a workspace, in which each variable I declare
is automatically global, and can be reached from all views, i.e. from
the command line interpreter as well as form the OLE environment, no
matter where they are declared.
I try to do something similar in Python:
- I want to run an initialization part just once
- I want to run some testcode often and interactively
So the most simple example:
#Initialization
import time;
A = 5;
#code under test
x=time.time();
# do something time consuming
print 1000*(time.time()-x);
Now if I run the initialization part, manual line by line in the command
line interpreter, I can run the code under test as often as I want.
My real initilization code is much larger and therefor very clumsy to
run line by line in the command line interpreter.
Is there a way to run the initialization code from a script(file) once,
to achieve the same effect ?
thanks,
Stef Mientki
