uv and VSCODE how to use this on different machines and not break

 You have a system at the office and at home You use uv to manage python projects and venvs by default uv puts the interpreter in a hidden directory locally, on windows something like '"C:\Users\cl\AppData\Roaming\uv\python\cpython-3.12.9-windows-x86_64-none\python.exe'    This is butt, because only one machine will have this exact directory structure. How to fix this. delete .venv uv sync    # uses uv.lock to see what you've already downloaded and recreate a working venv locally next: Create a folder named .vscode in your project root (if you haven't already). Create a file inside it named settings.json . Add this configuration: JSON { "python.defaultInterpreterPath" : "${workspaceFolder}/.venv/Scripts/python.exe" , "python.terminal.activateEnvironment" : true } After doing all of this vscode may still show squigglies like it can't find the right interpreter. How to fix this. ctrl + shift + p find "developer: Reload...

How to use UV (windows)-- CL notes from Salesforce ticket 8869

 UV replaces things like pip and pyenv, it is one tool to do most everything for interpreter management, virtual env, and adding packages--all the basic Python "use venvs and leave your system python alone" necessities. This ticket goes over installing UV on Windows, working within virtual environments, and using VSCODE as IDE Your steps will vary if: --You are not using Windows as OS --You are not using VSCODE as IDE --You are not using VENVs ============= DO THIS FROM ELEVATED CMD PROMPT IN WINDOWS! 3/14/2025 08:41:34 Good link for UV https://www.youtube.com/watch?v=Zn5tmx0ynw8 good vid: https://www.youtube.com/watch?v=AMdG7IjgSPM **is UV already installed?** from cmd or terminal run uv if it throws up a "here are UV commands you can use" you are good to go. If not, keep reading about how to install. **INSTALL UV AND ADD TO WINDOWS SYSTEM PATH*** #install uv from "system" python using PIP (not sure if this is the best way to do it but it works) python -m...

Python POOP: "name mangling"--how to make class data private or public (odd in Python!)

https://www.youtube.com/watch?v=6cvFzLB6hbA they way Python OOP ("Poop") deals with private and public data in classes is strange indeed. by default all class attributes and methods are public (so, no encapsulation, of any kind, at all) There is no reserved words "public" private protected that the interpreter recognizes. To get around this python employs "name mangling": __x = 7 two underscores means the variable or method is private to the class. If you go outside the class and try to print __x you get an error. However, you can still see the value for this name-mangled variable:  _classname.__x  (one underscore classname, dot, two underscores, variable name) So it's not really private, it is psuedo-private.   Whatever.

MAKING SOME POOP==Python classes constructor and instantiating; class variables

https://www.youtube.com/watch?v=ZDa-Z5JzLYM    << intro video on POOP https://www.youtube.com/watch?v=BJ-VvGyQxho&t=1s << class variables. SYNTAX IS A BIT FUCKED UP FOR PYTHON POOP. Easiest way to get going: class Employee:     pass Constructor uses odd syntax "self". I hear self can be anything you want, not sure why they didn't use something like (UserInstantiated) Self can be anything but everyone uses self --we require attributes for firstname, lastname, and pay. class Employee:      def __init__(self, firstname, lastname, pay):          self.first           self.last            self.pay           self.email = first + '.' + last + '@piscesinc.com'      Once constructor is set, you instantiate: emp1 = Employee("charlie", "lamm",50000) emp2 = Employee("Bob", "Kaake",70000) To add a method--creating ful...
