Spaces in String Variable

Hi,

I have an issue with my script related to the space in the string variable (see below). If "MinNPP" is used instead it works fine.
I've also tried setting the variable as str(arcpy.GetParameterAsText(6)) but it doesn't work either. The variable is set as String data type in the tool; Filter = Value list. Version used is 10.0

Variable:

NPPEquation = arcpy.GetParameterAsText(6)

Process:

if NPPEquation == "Min NPP1":

Thank you

Toni

Have you tried using print NPPEquation just to see exactly what is being returned by the GetParametersAsText.
It should work, but only if NPPEquation is exactly "Min NPP1"
Not much, I know but good luck,
Neil

Hi Toni,

So do you have added "Min NPP1" to your filter value list? Are you sure there's no trailing space or whatsoever?

Thanks a lot guys.

I tried the print NPPEquation and it works fine. "Min NPP1" is one of the values in the filter list.

The thing is that I've set the output raster dataset to include the name of the NPPEquation ("Min NPP" for example).
So I guess is not the right approach to have spaces in the string variable names. Not sure if there is a way round that...

Cheers

Toni

rasters don't like spaces in their names if this is indeed an output name

Toni,

You can use an IF statement to replace the space using python's replace method. Example:

if " " in NPPEquation:
    NPPEquation = NPPEquation.replace(" ", "_")
