Quick tip on testing existence of a variable...

I'm writing a plugin and as data comes in, for some of it, I want to update it in a variable. Now, my plan is to have the plugin create the variable, and then update it, but ideally, I want to test if it's already there (from running the plugin previously...), and if not, THEN create it.

I'm thinking this will work...

Code: Select all

      try:
         newvar = indigo.variables["MyVarName"]
      except:
         newvar = indigo.variable.create("MyVarName")
         


But I'm wondering if something like this might do it too..

Code: Select all

if "MyVarName" is in indigo variables[]:
logic
logic

Any thoughts on which of these is preferred?

Yes, the preferred technique would be:

Code: Select all

if "myVarName" is not in indigo.variables:
  someVar = indigo.variable.create("MyVarName")
else:
  someVar = indigo.variables["myVarName"]
