array of Tkinter variables?

[Jo Schambach]

I want to build an array of entry widgets in python with Tkinter that
all have similar textvariables. I was hoping that I could use an array
of StringVar variables to attach to these widgets, so that I can loop
through the widget creation. But my simple minded approach failed:

for i in range(32):
self.dllAdjust[i] = StringVar()
self.dllAdjust[i].set('000')

gives me the following error:

File "./config.py", line 787, in setDefaultVals
self.dllAdjust[i] = StringVar()
AttributeError: Configurator instance has no attribute 'dllAdjust'
("Configurator" is the class in which this code fragment appears)

How does one define an array of StringVar? If that is not possible, what
would be an alternative approach to the idea in the code fragment above?

I think what you want is something like:

self.dllAdjust=[]
for i in range(32):
sv=StringVar()
sv.set('000')
self.dllAdjust.append(sv)
(not tested)
