Python模块化开发组织代码程序示例

[日期:2017-01-20] 来源:Linux社区  作者:babyfish13 [字体: ]

样例包含三部分代码,周的处理函数部分、业务数据处理部分及多线程跑批调度处理部分。

代码按功能分类存放,有助于使代码更清晰,通过from...import的方式,使代码重复使用。

另外,多线程的调用部分,有效处理了程序先后依赖及多程序串并行跑批问题,为以后相似问题的处理,提供了借鉴。

1、周处理函数

/Users/nisj/PycharmProjects/EsDataProc/Remain_Data_Proc/WeekCalc.py

    wk_l = []
    for wl in sorted(list(week)):

                batch_week_list.append(([curr_week, his_week],None))
    return batch_week_list

def getWeekFristday(weekflag):
    yearnum = weekflag[0:4]  # 取到年份
    weeknum = weekflag[5:7]  # 取到周
    stryearstart = yearnum + '0101'  # 当年第一天
    yearstart = datetime.datetime.strptime(stryearstart, '%Y%m%d')  # 格式化为日期格式
    yearstartcalendarmsg = yearstart.isocalendar()  # 当年第一天的周信息
    yearstartweekday = yearstartcalendarmsg[2]
    yearstartyear = yearstartcalendarmsg[0]
    if yearstartyear < int(yearnum):
        daydelat = (8 - int(yearstartweekday)) + (int(weeknum) - 1) * 7
    else:
        daydelat = (8 - int(yearstartweekday)) + (int(weeknum) - 2) * 7

    week1day = (yearstart + datetime.timedelta(days=daydelat)).date()
    return week1day

# Batch Test
# his_week_list = ['2015#46', '2015#45', '2016#2']
# batch_week_list = []
# for his_week in his_week_list:
#    batch_week_list.extend(hisRunWeekList(his_week))
# print batch_week_list
# print getWeekFristday('2016#11')
# his_week = '2016#11'
# print currWeekList(his_week)

# print getNowYearWeek()
