If you have setuptools you can use $ easy_install -U pycorreios Otherwise, you can download the source from GitHub and run $ python setup.py install
Some simple examples of what pyCorreios code looks like: # -- coding: utf-8 -- from pycorreios import Correios
test = Correios().frete(Correios().SEDEX,'44001535','03971010',10,18,8)
if test['Erro'] != '0':
print 'Deu erro! :('
print test['Erro']
print test['MsgErro']
else:
print "Valor: R$%s\nPrazo de Entrega: %s" % (test['Valor'],test['PrazoEntrega'])
print
other_test = Correios().cep('03971010')
for tag_name in other_test.keys():
print tag_name + ': ' + other_test[tag_name]
