more looping help?

for month in range(1, 13):
    folder = folder = f'{year}-{month:0>2}'
    os.makedirs(os.path.join('.', folder))

Thanks Buran. That worked.
Can you explain the code to me and, more importantly, your thought process to arrive at this code?
* How do I get past the point of just staring at a blank screen having no real idea how to start?
* Where did month come from? It's not a variable like 'year' which uses the datetime module.
* Why is the f-string using 2 folder-equals (folder = folder = f')? I've never seen that.
* What are you joining with os..join? What is the '.' pointing to, current folder? If so, where's the backslash (.\)?

Thanks for the help.
I quickly (for me ) coded up a script to create a complete folder-subfolder structure for a tax year. This will be a yearly time saver and I'm quite proud of myself

BTW, for anybody here for future reference.

required dependencies:

import os
import datetime
year = datetime.now().year

The above forLoop replaces these lines of code:

os.makedirs('.\\' + str(year) + '-01')
os.makedirs('.\\' + str(year) + '-02')
os.makedirs('.\\' + str(year) + '-03')
os.makedirs('.\\' + str(year) + '-04')
os.makedirs('.\\' + str(year) + '-05')
os.makedirs('.\\' + str(year) + '-06')
os.makedirs('.\\' + str(year) + '-07')
os.makedirs('.\\' + str(year) + '-08')
os.makedirs('.\\' + str(year) + '-09')
os.makedirs('.\\' + str(year) + '-10')
os.makedirs('.\\' + str(year) + '-11')
os.makedirs('.\\' + str(year) + '-12')
