Python：根据季度数计算月份、季度详细信息

Question

我正在尝试根据季度数计算月份、季度详细信息

示例：当前日期 = 2017 年 4 月 29 日

I/p:

No_of_quarters=6

O/p:

Quarters = ["Q1-2016","Q2-2016", "Q3-2016", "Q4-2016", "Q1-2017", "Q2-2017"]
Months = ["Jan-2016","Feb-2016","Mar-2016","Apr-2016","May-2016","Jun-2016","Jul-2016","Aug-2016","Sep-2016","Oct-2016","Nov-2016","Dec-2016","Jan-2017","Feb-2017","Mar-2017","Apr-2017"]

有没有我可以重复使用的预定义函数？或者我需要使用以下方式计算

today = datetime.date.today()
month = int(today.strftime("%m")) - 1 
quarter = month / 3 + 1
quarter_Name = "Q" + str(quarter)  + "-" +  today.strftime("%Y")
month_name = today.strftime("%b") + "-" +  today.strftime("%Y")

Answer 1

Try timeindex in pandas

示例：

import pandas as pd
prng = pd.period_range('01/01/2017', '04/29/2017', freq='Q')

print(prng)
PeriodIndex(['2017Q1', '2017Q2'], dtype='period[Q-DEC]', freq='Q-DEC')

# Change freq to 'M'
prng = pd.period_range('01/01/2017', '04/29/2017', freq='M')

print(prng)
PeriodIndex(['2017-01', '2017-02', '2017-03', '2017-04'],
             dtype='period[M]', freq='M')

Answer 2

使用 pandas 和 no_of_quarters 输入

import pandas as pd
import datetime

No_of_quarters=6

today = datetime.date.today()
month = pd.Period(today, freq='M')
quarter = month.asfreq('Q-DEC')

print "Quarters:"
for x in range (0,No_of_quarters-1):
    print quarter-x

print "Months:"
for x in range (0,(No_of_quarters*3)-1):
    print month-x
