python 中hive 取日期时间的方法

#!/usr/bin/env python3
import sys
import os
import time, datetime

sys.path.append(os.getenv(‘HIVE_TASK‘))
from HiveTask import HiveTask
ht = HiveTask()

day_dt = ht.data_day_str
buy_begin = ht.oneday(-80)
buy_end = ht.oneday(-20)
day_begin = ht.oneday(-5)
day_end = ht.oneday(0)

print (day_dt)
print (buy_begin)
print (buy_end)
print (day_begin)
print (day_end)

print (‘ok‘)
