Either store the checkboxes in an array or hash/dictionary. If that's
not practical, then
You can use strings to build the code and use eval to execute the string
as code. Ex:
for i in range(10):
code = "%d + %d" % (i, i)
print eval(code)
Don't do this. You want
for idx in range(10):
setattr(self, 'checkbox_%i' % idx)
Assuming create_checkbox() is the function to create a checkbox, this will
create a list of 25 checkboxes::
checkbox = [create_checkbox() for i in xrange(25)]
