get state code, state name and state abbreviation - Larz60+ - Oct-11-2017
The following code will create a json file containing data for US states and possessions,
and presents a method for retrieving any missing two fields based on the field that is known.
The main function has examples for each of these conditions.
The state code is the FIPS state code which is used in most all datasets provided to the public by
the US government.

There appears to be such in pypi already

RE: get state code, state name and state abbreviation - Larz60+ - Oct-11-2017
It was fun writing it

DeaD_EyE thanks, I'll use this.
I didn't even know this had been built into python (since 3.4) until you mentioned it.
It's worth exploring what's there, here's a sample that just touches the surface
(I could have made this look exactly like Linux ls, but I'm too tired to do so now).
from pathlib import Path
class SetPath:
def __init__(self):
self.make_paths()
def make_paths(self):
self.homepath = Path('.')
self.show_contents(self.homepath)
self.datapath = self.homepath / 'data'
self.show_contents(self.datapath)
self.zippath = self.homepath / '../ZipcodeData'
self.show_contents(self.zippath)
self.addrpath = self.zippath / 'ADDR'
# print([f'{x}\n' for x in addrpath.iterdir()])
self.show_contents(self.addrpath)
@staticmethod
def show_contents(folder):
print(f'\ndir {folder.name}')
for item in folder.iterdir():
if item.is_dir():
print(f' d..{item}')
else:
print(f' ...{item}')
