I prefer explicit loops over map and lambdas:

def magic_algorithm(another_list, count):
    length = len(another_list)
    result = []
    for i in xrange(length**count):
        number = ''
        for pos in range(count):
            # prepend the next digit
            number = another_list[i % length] + number
            i = i / length
        result.append(number)
    return result
