How do I access variable file in a script?

I have found a method that is so simple it's embarrassing! Not even worthy of a name like 'Hack3'!

params.py
Code: 
a = 22
b = 33
c = a + b

test_script.py
Code: 
import sys

Folder = "C:\\Users\\dh\Documents\\RotoAlibre\\Alibre\\Hack3"
execfile( Folder + "\\" + "params.py" )

print a, b, c

I saw references to using 'execfile' earlier but couldn't make it work and moved on. I since learned that because of the way Alibre Python is set up, the folder of execution is different the folder containing the file. So it's necessary to explicitly provide the correct path to the file.

Obviously this method is limited to use with parameters that remain constant throughout a script, but that's all was looking for. Maybe this solution was obvious to some readers of this thread but my explanations of what I was trying to achieve were not adequate.

Stefan,

I was not aware that the test "if p not in sys.path:" was not actually working. Thanks for pointing that out. I'll have to take a look at it, although as it stands I'll be abandoning that code as I implement my "embarrassingly" simple solution.

It seems that it's doing the same without the "p-check".
It makes the sys.path longer each time you run the script. If the script is running, you can do the loop without making the path longer.
So i think it would be the best if andy @ajayre can take a look on it.

Edit: If you deactivate and reactivate (Launch) Alibre Script, the path gets reset. Running the script again, everything starts over.


Regards
Stefan

This code isolates the problem. It seems that 3 specific paths are added on each time a script is run, regardless of whatever script itself is doing.

Code: 
import sys

print "---- Running the script: ---- "

print len(sys.path)
for i in sys.path:
  print i

print

Results of 3 runs:
Code:

---- Running the script: ----

Hello R-man,

if you take a look in post #24 you will see that it makes a difference to do it in the console or via script...
Definitely a thing for Andy to judge if it needs to be corrected.

If the script has been saved or loaded then use the built in variable 'ScriptFolder' to get the current script location. Then you can do:

Code: 
execfile(ScriptFolder + "\\" + "params.py" )

Just a note on paths.
You can escape the special function of backslash with another backslash like so:
Code: 
Folder = "C:\\Users\\dh\Documents\\RotoAlibre\\Alibre\\Hack3"
Or convert to forward slash like so:
Code: 
Folder = "C:/Users/dh/Documents/RotoAlibre/Alibre/Hack3"
Or just use an r in front of the string to use it in its raw form like so:
Code: 
Folder = r"C:\Users\dh\Documents\RotoAlibre\Alibre\Hack3"
