How to pull from multiple lists to make a new directory

Question

I'm trying to pull data from two different lists in order to make a new directory. But Python says that the second list queue is not defined when I try to run it.

import csv
import time
import os, sys
from datetime import date

queuelist = ['ONE']
yearlist = ['2013']

year = str(date.today().year)
month = str(date.today().month)

for year in yearlist and queue in queuelist:
    os.mkdirs('{0}\{1}'.format(queue,year))

`But Python says that the second list queue is not defined` - that's because, well, `queue` variable is not defined. — alecxe, May 16 '16 at 13:48

You probably want either a nested loop ...

for year in yearlist:
    for queue in queuelist:
        # ... to do stuff for every possible year/queue combination

or you want to zip the two lists ...

for year, queue in zip(yearlist, queuelist):
    # ... to do stuff with year-queue pairs of same index

thank you, would I need to add another colon by `yearlist` too? For the nested loop – iOSecure May 16 '16 at 14:35
