Thanks Peter

(2) attrs is a dict, so iterating over it will lose the values. Are you sure
you want that?

Yes initially I want just the keys as a list so I can choose to filter them out
to only the ones I want.

Thanks very much will get my function up and working.

A couple notes:
-I think the Python interpreter actually sends its output to stderr, so to
capture it you'd probably want it to go to the same place as stdout, so use
stderr = subprocess.STDOUT
-You're only reading 1 line out output for each thing, so if 1 command creates
multiple lines of out

Not always. If your code supported Python 2 in the past, or third-party

Hi.
I want to use a function argument as an argument to a bs4 search for attributes.
I had this working not as a function
# noms = soup.findAll('nomination')
# nom_attrs = []
# for attr in soup.nomination.attrs:
# nom_attrs.append(attr)
But as I wanted to keep finding other ele

check the github page[0], or using git tag --contains, you will find v2.7.x

Nope, that would be the effect of "and", not "or".
"a" is b"b" and "fallback"
False
"a" is b"b" or "fallback"
'fallback'
You seem to be caught in your wrong mental model. I recommend that you let
the matter rest for a day or so, and then look at it with a fresh eye.

Technically, the comparison used is:
