Change your locale.

import locale

# Set to users preferred locale:
locale.setlocale(locale.LC_ALL, '')
# Or a specific locale:
locale.setlocale(locale.LC_NUMERIC, "en_DK.UTF-8")
print(locale.atof("3,14"))

See 
http://docs.python.org/3/library/locale.html#background-details-hints-tips-and-caveats 
for the background.
