Why would any of those work? None were defined as variables, and python, being a sane language developed for people who are not insane, does not define variables for you unless you do it yourself :p
You'd access them just as you would the elements of any list: through an index.

>>> import tkinter as tk
>>> root = tk.Tk()
>>> categories = []
>>> for i in range(5):
... cat = tk.StringVar()
... cat.set("test: {0}".format(i))
... entry = tk.Entry(root, textvariable=cat)
... entry.pack()
... categories.append(cat)
...
>>> categories
[<tkinter.StringVar object at 0x001B7DB0>, <tkinter.StringVar object at 0x01632AD0>, <tkinter.StringVar object at 0x001EE710>, <tkinter.StringVar object at 0x001EE790>, <tkinter.StringVar object at 0x001EE810>]
# at this point, the window has 5 entry fields. I changed the contents of the second to say "spam"
# here's how we'd retrieve it's contents later...
>>> categories[1].get()
'spam'
