我是靠谱客的博主务实钢铁侠，这篇文章主要介绍python获取每年的季度，月份，现在分享给大家，希望可以做个参考。

参数：年份，跳跃月数，

如果获取每个季度，step=3；半年，step=6

返回：起始和结束

import datetime
import calendar

def year_by_step(year,step):
    start = str(year) + "0101"
    jump = int(step)
    try:
        datetime.datetime.strptime(start,"%Y%m%d")
    except Exception as result:
        raise Exception("参数格式必须是yyyy如：1999,%s" % result)
    result = []
    for i in range(1,13,jump):
        if i+jump-1 > 12:
            break;
        month_start,month_end = ("%02d" % int(i),"%02d" % int(i-1+jump))
        range_day = calendar.monthrange(int(year),int(month_end))[1]
        m_start = str(year)+month_start+"01"
        m_end = str(year)+month_end+str(range_day)
        result.append((m_start,m_end))
    return result
                      
测试：
print(year_by_step(2019,3))
结果：
[('20190101', '20190331'), ('20190401', '20190630'), ('20190701', '20190930'), ('20191001', '20191231')]
