Python Installation

reference - Python Programmer

The following note is for windows systems

Download the Python version

Download the official python version for Windows Choose Custom installation within python installer and choose a custom path dedicated to that version
For example: D:\python\3.13.3

Do not add installation to path

Creating Python Project

Create a python project directory
For example: D:\projects\python\project1

Create a python virtual environment for the project

cd D:\projects\python\project1
 
D:\python\3.13.3\python -m venv environment_name

This will create a python virtual environment under project1 that depends on python 3.13.3 version only.

Virtual environments in Python are like isolated workspaces where you can install dependencies without affecting the system-wide Python installation or other projects.

Activiate The Virual Environment

Validate if the virutal environment is created or not by using the tree command

cd D:\projects\python\project1
 
tree

If environment is created, activate the environment using the activate script

cd D:\projects\python\project1
 
environment_name\Scripts\activate

Once activated, check if python is active within the environment

python --version
# should output the version used to create the environment
