Thank you. many fonts squish together repeated underscores in the display so it's hard to see this visually, I've had a problem or two of this nature as well (a keyboard that got a little "bouncy" and more than once doubled keypresses).

Python install failing. Install log is available.
Hi, I've usually had problems installing python, typically pip breaking. This time it's simply not installing correctly when run as administrator, and not at all when run as non-administrator. As administrator, it's not installing for other users as I believe it should. It's certainly not adding the python path correctly *for all users* (install option "add python to environment variables"), from a command console run as admin: C:\WINDOWS\system32>whoami antik\administrator C:\WINDOWS\system32>echo %PATH% C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\Program Files\dotnet\;C:\Program Files\TortoiseGit\bin;C:\Users\Administrator\AppData\Local\Programs\Python\Python39\Scripts\;C:\Users\Administrator\AppData\Local\Programs\Python\Python39\;C:\Users\Administrator\AppData\Local\Microsoft\WindowsApps;C:\Users\Administrator\.dotnet\tools It's there, but from a non-admin console (I work just a normal user): C:\Users\jan>whoami antik\jan C:\Users\jan>echo %path% C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\Program Files\dotnet\;C:\Program Files\TortoiseGit\bin;C:\Users\jan\AppData\Local\Microsoft\WindowsApps;C:\Users\jan\AppData\Local\Programs\Git\cmd So no python path added. When install is run as non-administrator it seems to fail outright due to lack of privileges. The install log for this non-admin is available on request (I'd rather not attach it as it contain have sensitive info, but can post it publicly if really wanted. It's 60K). I tried elevating my non-admin account to admin then re-running the python installer, it broke. Trying to reinstall it has now lost all associations with the .py extension. I don't know what's going on. My build depends on python and obviously that's failing now. I've worked around it by downloading and unzipping python embedded, setting the file association and hardcoding file paths, but that's certainly not ideal. Any thoughts?

The only thing comprising an introduction is a brief paragraph that starts the chapter and has no attribution. HTH, boB Stepp -- https://mail.python.org/mailman/listinfo/python-list

Use Chrome's / Firefox's dev-tools in python
My school has a website for homework called pronote (no problem if you don't know it). After logging in on parisclassenumerique.fr (works with selenium but I cant get requests to work), I want to read one of the packets that is sent: All the info about my day, my homework, etc. are in there and it is the perfect file: header request response stack trace The file's download address looks random. The login works only for a limited period of time in the same browser. Any ideas for using that tool of Firefox or same of Chrome? Thanks! -- https://mail.python.org/mailman/listinfo/python-list

It's not going to be easy to replicate that in Python without actually providing your login credentials. I'd say the easiest approach is going to be a hybrid of Python to do your processing, with some JavaScript to collect the request information. But it all depends on how much you want to automate this, and how much effort you're willing to put in. For instance, you could write a Chrome extension that is aware of the traffic, or perhaps it'd be sufficient to just paste some JavaScript code into the Dev Tools console before you send the request.

The preface does say the third edition is a major rewrite, so I suppose there will be significant differences from the 2nd edition which I don't own. boB Stepp -- https://mail.python.org/mailman/listinfo/python-list
