It seems your string is UTF-8.  \xc2\xb0 is UTF-8 for DEGREE SIGN.  If you 
type non-ASCII characters in source code, make sure to declare the encoding 
the file is *actually* saved in:

# coding: utf-8

s = '''48° 13' 16.80" N'''
q = s.decode('utf-8')

# next line equivalent to previous two
q = u'''48° 13' 16.80" N'''

# couple ways to find the degrees
print int(q[:q.find(u'°')])
import re
print re.search(ur'(\d+)°',q).group(1)
