Creating StringVar() class variables

Question

I'm building a GUI using Tkinter and I've to create class StringVar atributes depending on a variable called initial_numbers. If initial_numbers is 5, I've to create 5 StringVars() with the name self.string_var plus a number so I can identify them.

If:

self.initial_numbers = 5

I've to create

self.string_var0 = StringVar()
self.string_var1 = StringVar()
self.string_var2 = StringVar()
self.string_var3 = StringVar()
self.string_var4 = StringVar()

After creating them, I want to add them to a list called stringList

What I've tryed this, but of course it's not working.

self.initial_numbers = 5
stringList = []
for i in xrange(int(self.initial_numbers)):
    self.string_var+str(i) = StringVar()
    self.string_var+str(i).set("test")
    stringList.append(self.date_string+str(i))

Thanks in advance.

You already put them in a list; why create five individual variables ? Put them in the list directly, and use the index to access them.

self.string_var = []                        # create empty list
for i in xrange(self.initial_numbers):
    self.string_var.append(StringVar())     # append to list
    self.string_var[i].set("test")          # access var at index i
