Work Environment

VS Code

A code editor. It's free, open source, and runs everywhere (even your Ipad).

Install

Source code

• Really good IntelliSense
• Debugging
• Integrated version control (Git)
• Highly customizable

Overview

Useful Commands

• ctrl+shift+p -> Most useful, opens the command palette
• ctrl+k, ctrl+s -> Keyboard shortcuts, away with the mouse!
• ctrl+b -> Toggle Explorer
• ctrl+` -> Toggle Terminal

Use cases

Coding

Virtual environments

Isolate workspaces on a per-project basis

Template Project Structure:

• project_name
  • .venv
  • .vscode
  • .gitignore
  • project_name
    • __init__.py
    • main.py
  • requirements.txt

Steps

1. ctrl+shift+p -> Python: Create Environment

2. ctrl+shift+` to open new terminal in .venv

3. pip install -r requirements.txt

4. Create repo online and initialize it locally

   echo "# project_name" >> README.md
   git init
   git add README.md
   git commit -m "first commit"
   git remote add origin [email protected]:username/project_name.git
   git push -u origin master

For management of different python environments use pyenv

Code Generation:Function that gets the ground state of a given Hamiltonian H

• Code generation Function that gets the ground state of a given Hamiltonian $H=\begin{bmatrix} 0 & 1 & 1 & 0\ 1 & 0 & 0 & -1\ 1 & 0 & 0 & -1\ 0 & -1 & -1 & 0 \end{bmatrix}$
