网上的几个代码都没有注释，代码格式也不太好，特此记录一下
from datetime import datetime
import datetime as dt
import calendar
# 母亲节
month_number = 5 # 五月
sunday_index = 0
date_value_index = 0
cal = calendar.Calendar(firstweekday=6)
year=dt.datetime.now().year # 获取当年的年份
weeks = cal.monthdays2calendar(year, month_number)
week_index = 1 # 第二个星期天
if weeks[0][sunday_index][date_value_index] == 0: # date为0说明不是5月的第一周
week_index += 1
result = weeks[week_index][sunday_index][date_value_index]
m_day='05-{0}'.format(str(result).zfill(2))
# 父亲节
month_number = 6
sunday_index = 0
date_value_index = 0
cal = calendar.Calendar(firstweekday=6)
year=dt.datetime.now().year # 获取当年的年份
weeks = cal.monthdays2calendar(year, month_number)
week_index = 2
if weeks[0][sunday_index][date_value_index] == 0: # date为0说明不是6月的第一周
week_index += 1
result = weeks[week_index][sunday_index][date_value_index]
f_day='06-{0}'.format(str(result).zfill(2))
