近期一个项目要写一个类，跟同学争执不下，特来请教各位大佬
import time
class SchoolDate(object):
def __init__(self, school_time):
self.weeks = 1
self.what_day = 1
self.school_time = time.strptime(school_time, "%Y-%m-%d")
def get_term(self):
timestamp = time.mktime(self.school_time)
#计算开学前周日的时间戳
first_week_timestamp=timestamp- 86400* int(time.strftime("%w",self.school_time))
now_timestamp = time.time()
self.what_day = time.strftime("%w",time.localtime(now_timestamp))
#周数 = (当前时间戳 - 开学周日的时间戳) / 7 天 +1
self.weeks = int((time.time() -first_week_timestamp)/ (86400*7)) + 1
if self.weeks < 1:
self.what_day = 1
self.weeks = 1
return self
def weeks(self):
return self.weeks
def day(self):
return self.what_day

初级写法，敬请吐槽！！
