Creating a list of file names based on arithmetic of the month and year

How can I list the numbers 01before 12(one for each of the 12 months) so that the current month is always the last, where the oldest of them is the first. In other words, if the number is greater than this month, then this was last year.

eg. 02- February 2011 (the current month right now), 03- March, 2010 and 09- September 2010, but 01- January 2011. In this case, I would like to have [09, 03, 01, 02]. This is what I do to determine the year:

for inFile in os.listdir('.'):
    if inFile.isdigit():
    month = months[int(inFile)]
       if int(inFile) <= int(strftime("%m")):
           year = strftime("%Y")
       else:
           year = int(strftime("%Y"))-1
       mnYear = month + ", " + str(year)

I have no idea what to do next. What should I do here?

Update:

I think I better downloaded the entire script for a better understanding.

#!/usr/bin/env python

import os, sys
from time import strftime
from calendar import month_abbr

vGroup = {}
vo = "group_lhcb"
SI00_fig = float(2.478)
months = tuple(month_abbr)

print "\n%-12s\t%10s\t%8s\t%10s" % ('VOs','CPU-time','CPU-time','kSI2K-hrs')
print "%-12s\t%10s\t%8s\t%10s" % ('','(in Sec)','(in Hrs)','(*2.478)')
print "=" * 58

for inFile in os.listdir('.'):
    if inFile.isdigit():
        readFile = open(inFile, 'r')
        lines = readFile.readlines()
        readFile.close()

        month = months[int(inFile)]
        if int(inFile) <= int(strftime("%m")):
            year = strftime("%Y")
        else:
            year = int(strftime("%Y"))-1
        mnYear = month + ", " + str(year)

        for line in lines[2:]:
            if line.find(vo)==0:
                g, i = line.split()
                s = vGroup.get(g, 0)
                vGroup[g] = s + int(i)

        sumHrs = ((vGroup[g]/60)/60)
        sumSi2k = sumHrs*SI00_fig
        print "%-12s\t%10s\t%8s\t%10.2f" % (mnYear,vGroup[g],sumHrs,sumSi2k)
        del vGroup[g]

When I run the script, I get the following:

                  (in Sec)  (in Hrs)      (*2.478)

All of these methods work whether Jan is "0" or "1". Just change any link range(1,13)to range(0,12)depending on the agreement.

Edit

If I understand what you are doing, this code will help:

import datetime

def prev_month(year,month,day):
    l=range(1,13)
    l=l[month:]+l[:month]
    p_month=l[10]
    if p_month>month:
        p_year=year-1
    else:
        p_year=year
    return (p_year,p_month,1)

def next_month(year,month,day):
    l=range(1,13)
    l=l[month:]+l[:month]
    p_month=l[0]
    if p_month<month:
        p_year=year+1
    else:
        p_year=year
    return (p_year,p_month,1)

year=2011
month=2
t=(year-1,month,1)
ds=[]
for i in range(1,13):
    print datetime.date(*t).strftime('%m, %y')
    t=next_month(*t)

Conclusion:

02, 10
03, 10
04, 10
05, 10
06, 10
07, 10
08, 10
09, 10
10, 10
11, 10
12, 10
01, 11

Just put the appropriate file name format in the method strftime()...

Hope this is what you are looking for ...
