Python Errors

[kendias]

Thanks Buran.
I am trying this script to convert from decimal to degrees to use on Google Maps but get errors:

# -*- coding: utf-8 -*-
import webbrowser
import string

def to_degrees(lats, longs):
# Convert string forms from ddmm.mmmm to dd°mm'ss.ss“

   lat_deg = lats[0:2]
   lat_mins = lats[2:4]
   lat_secs = round(float(lats[5:])*60/10000, 2)
   lat_str = lat_deg + u'°'+ lat_mins + string.printable[68] + str(lat_secs) + string.printable[63]

   lon_deg = longs[0:3]
   lon_mins = longs[3:5]
   lon_secs = round(float(longs[6:])*60/10000, 2)
   lon_str = lon_deg + u'°'+ lon_mins + string.printable[68] + str(lon_secs) + string.printable[63]

   return [lat_str, lon_str]


#error
