I am looking for a simple Git command that provides a nicely formatted list of all files that were part of the commit given by a hash (SHA-1), with no extraneous information. I have tried: git show a303aa90779efdd2f6b9d90693e2cbbbe4613c1d Although it lists the files, it also includes unwanted diff information for each.

Is it possible to add a key to a Python dictionary after it has been created? It doesn't seem to have an .add() method. You create a new key/value pair on a dictionary by assigning a value to that key d = {'key': 'value'} print(d) # {'key': 'value'} d['mynewkey'] = 'mynewvalue' print(d) # {'key': 'value', 'mynewkey': 'mynewvalue'} If the key doesn't exist, it's added and points to that value.

For a web page that exists, but for which a user does not have sufficient privileges (they are not logged in or do not belong to the proper user group), what is the proper HTTP response to serve? 401 Unauthorized? 403 Forbidden? Something else? What I've read on each so far isn't very clear on the difference between the two. What use cases are appropriate for each response? A clear explanation f..
