From the `os` docs:
os.environ
A mapping object representing the string environment.
From the `dict` docs (`dict` being the built-in and prototypical mapping class):
D.get(k[,d]) -> D[k] if k in D, else d. d defaults to None.
From this, I conclude that the environment variable `some_env` does
not exist for you, thus .get() returns None, thus causing an error
when you try and concatenate it with a string.
Solution: Either fix things so the environment variable does exist or
add code to handle the case of the environment variable not existing.
Cheers,
Chris
