+
+Getting started with data science involves setting up a few key tools. In this guide, we'll walk through the installation of:
+
+1. Python
+2. Anaconda
+3. Jupyter Notebooks
+
+# 1. Python Installation
+
+Before installing a specific version of Python, it's good practice to check if you already have it installed and which version you're using.
+
+
+## Check Existing Python Installation
+
+To find the path of the current Python executable, use:
+
+```
+which python
+```
+
+To check the version of Python installed, run:
+
+```
+python -V
+```
+
+## Using `pyenv` for Python Version Management
+To manage different versions of Python, we'll use [pyenv](https://github.com/pyenv). pyenv simplifies the process of installing and switching between multiple Python versions.
+
+## Install `pyenv`
+
+You can install pyenv using Homebrew. Run the following commands:
+
+```
+brew update
+brew install pyenv
+```
+
+## Manage Python Versions with `pyenv`
+
+Here are some useful `pyenv` commands:
+
+1. List available python versions:
+```
+pyenv install -l
+```
+
+2. Install a specific Python version:
+```
+pyenv install 3.10
+```
+
+3. Set a global Python version:
+```
+pyenv global 3.10
+```
+
+4. Set a local Python version for a directory:
+```
+pyenv local 3.10
+```
+
+5. Upgrade `pyenv`
+```
+brew upgrade pyenv
+```
+
+# 2. Installing Anaconda
+
+Anaconda is a popular distribution for data science that simplifies package management and deployment.
+
+## Install Anaconda:
+
+1. Visit the Anaconda [website](https://www.anaconda.com/download) and download the installer for your operating system.
+2. Once the download is complete, run the installer and follow the on-screen instructions to complete the installation.
+
+# 3. Installing Jupyter Notebooks
+
+Jupyter Notebooks are an essential tool for data analysis and visualization.
+
+## Install Jupyter Lab
+
+```
+pip install jupyterlab
+```
+
+## Launch Jupyter Lab
+
+After installation, start Jupyter Lab with:
+
+```
+jupyter lab
+```
+
+This command will open Jupyter Lab in your web browser, where you can create and manage notebooks.
+
+# Summary
+
+By following these steps, you’ll have Python, Anaconda, and Jupyter Lab set up and ready for your data science projects. Each tool plays a crucial role in developing and managing your data science workflows efficiently.
