more looping help?

[pcsailor]

Hi,

I have another forLoop question if I may.

I want to loop through this line of code,

os.makedirs('.\\' + str(year) + '-01')

where with each iteration this part,

'-01'

increases by +1 integer and stops at 12.

Considering the many parts of that code line, I'm not sure how to do that.
Any ideas?
Thanks,
Phil
