Use String contents for checkbox name

[jcday]

Creating a number of checkbuttons with a for loop.
I store the name increment and would like to use the stored string as the checkbox name.

chkbox = "cb" + '%s' % i
self.chkbox  = Checkbutton(self.frame_content, text = aprlist[i-1])
         #   self.chkbox.grid(row = rowpos, column = col, padx = 5, pady = 2, sticky = 'w')

the question is, how to replace self.chkbox with the string content of chkbox

Any suggesstions?

Thanks
