Здравствуйте, программисты! Пожалуйста, помогите перевести решение с Paskal на Python

Проверки на корректность ввода и оптимизацию оставим на вашей совести.

from random import sample
number = map(str, sample(range(10), 4))
bulls = 0
print 'Komp zagadal chislo...'
while bulls != 4:
    hypothesis = raw_input('Vy schitaete, chto eto chislo: ')
    bulls = sum([number[i] == hypothesis[i] for i in range(len(number))])
    cows = sum([hypothesis[i] in number and hypothesis[i] != number[i] for i in range(len(number))])
    print 'bulls = {}; cows = {}'.format(bulls, cows)
print 'We are the champions!'

1. если в двух строках одинакоывый цикл - стоит задуматся
2. зачем len(number) если явно указано в sample(range(10), 4) что всегда только 4 знака?

from random import sample
number = map(str, sample(range(10), 4))
bulls = 0
print 'Komp zagadal chislo...'
while bulls != 4:
    bulls = cows = 0
    hypothesis = raw_input('Vy schitaete, chto eto chislo: ')
    for i in xrange(4):
        if number[i] == hypothesis[i]:
            bulls += 1
        elif hypothesis[i] in number:
            cows += 1
    print 'bulls = {}; cows = {}'.format(bulls, cows)
print 'We are the champions!'
