Python

Install and manage Python locally (Windows, macOS, Linux) using official installers, system packages, or pyenv; create virtual environments.

🧾 Overview

Python is used for bots, APIs, automation, scripting, and data tasks. Local installation allows you to install dependencies and test before deploying to Discloud.

📥 Installation

🪟 Windows

1

Download the latest Python 3 installer from https://www.python.org/downloads/

2

Check "Add Python to PATH" and complete installation.

3

Reopen terminal and verify

python --version
pip -V

4

Create optional virtual environment

python -m venv .venv
.venv\\Scripts\\activate
pip install --upgrade pip

🐧 Linux

Debian/Ubuntu

sudo apt update
sudo apt install -y python3 python3-pip python3-venv
python3 --version
pip3 -V
python3 -m venv .venv
source .venv/bin/activate

Fedora

sudo dnf install -y python3 python3-pip
python3 --version
pip3 -V
python3 -m venv .venv
source .venv/bin/activate

Arch

sudo pacman -S --needed python python-pip
python --version
pip -V
python -m venv .venv
source .venv/bin/activate

pyenv

Dependencies (Debian example):

sudo apt update
sudo apt install -y build-essential libssl-dev zlib1g-dev \
libncurses5-dev libffi-dev libbz2-dev libreadline-dev libsqlite3-dev \
liblzma-dev wget curl

Install & configure:

curl https://pyenv.run | bash
echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrc
echo 'command -v pyenv >/dev/null || export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(pyenv init -)"' >> ~/.bashrc
source ~/.bashrc
pyenv install 3.12.4
pyenv global 3.12.4
python --version

🍎 macOS

Installer

Download from python.org and run, then:

python3 --version
pip3 -V

Homebrew

brew update
brew install python
python3 --version
pip3 -V

---

✅ Verification

python --version
pip -V

If distro uses python3, substitute accordingly.

If your distribution uses python3 invoke that instead of python.

🗂 Virtual Environments

What it is: A virtual environment is an isolated directory tree containing its own Python interpreter and installed packages, separate from your global (system) Python.

Why use it:

• Keeps project dependencies isolated (one project can use requests==2.31, another requests==2.29).

• Avoids needing administrator / system-wide installs.

• Prevents accidental conflicts with OS packages or other projects.

• Makes requirements.txt reflect only what the project actually needs (reproducibility when deploying or sharing).

• Lets you test upgrades safely (create a new env, install, compare behavior).

Create & activate:

python -m venv .venv
source .venv/bin/activate  # Windows: .venv\\Scripts\\activate

Install dependencies & capture versions:

pip install -r requirements.txt
pip freeze > requirements.txt
