file io - Python error: list indices must be integers, not unicode -

there problem: i'm trying numbers tkinter's text widget(get's text file) way:

text = self.text_field.get(1.0, 'end')     s = re.findall("\d+", text)

s returns this:

[u'0', u'15', u'320', u'235', u'1', u'1', u'150', u'50', u'2', u'2', u'20']

than try add tags text widget:

for in s: self.text_field.tag_add('%s', '5.0', '6.0') %s[i]

and gives error:

list indices must integers, not unicode

thanx helping me :)

in python when do

for x in l:     ...

inside body loop x list element, not index.

in case correction needed use % i instead of % s[i].

if in other cases need both list element , index number common python idiom is:

for index, element in enumerate(l):     ...
