Как python возвращает значения методов?
Работающий вариант:from datetime import datetime

class school:
    address = "Hoggwart castle, 1 ave/34"
    school_number = 532
    teachers = 25
    scholars = 323
    __director = "Dumbledor"
    def __init__(self):
        self.init_time = datetime.now()
        print "Current time is %s" % self.init_time
    def school_address(self):
        a = "School andress is %s" % school.address
        print "print in school_address"
        return a

a = school()
print a.school_address()
Спасибо, было 2 ошибки, это и запутало :)
