+# Python Version Check Script
+
+This script checks for Python version 3.12 or higher and offers installation if requirements are not met.
+
+## Supported Operating Systems
+
+- **macOS** - uses Homebrew
+- **Ubuntu/Debian** - uses apt with deadsnakes PPA
+- **Arch Linux** - uses pacman
+
+## Usage
+
+1. Make the script executable:
+   ```bash
+   chmod +x scripts/check_python.sh
+   ```
+
+2. Run the script:
+   ```bash
+   ./scripts/check_python.sh
+   ```
+
+## What the Script Does
+
+1. **Python Version Check**: Searches for available Python commands and checks their versions
+2. **OS Detection**: Automatically detects the operating system
+3. **Installation Offer**: If a suitable version is not found, offers to install
+4. **Installation**: Uses the appropriate package manager for installation
+5. **Result Verification**: Ensures the installation was successful
+
+## Example Output
+
+### Successful Check
+```
+[INFO] Checking Python version requirements (>= 3.12)
+Found python3.12 version: 3.12.1
+[SUCCESS] Python requirement satisfied with python3.12
+[SUCCESS] Python version check passed!
+```
+
+### Installation on Ubuntu
+```
+[INFO] Checking Python version requirements (>= 3.12)
+Found python3 version: 3.10.6
+[WARNING] Python 3.12+ not found or version is too old
+[INFO] Detected OS: ubuntu
+[WARNING] Do you want to install/update Python? (y/N)
+y

+[INFO] Installing Python 3.12...
+[INFO] Verifying installation...
+Found python3.12 version: 3.12.7
+[SUCCESS] Installation successful! Python requirement satisfied with python3.12
+```
+
+## Requirements
+
+### macOS
+- Homebrew must be installed
+- If Homebrew is not installed, the script will provide installation instructions
+
+### Ubuntu/Debian
+- Sudo privileges for package installation
+- Internet access to add PPA
+
+### Arch Linux
+- Sudo privileges to use pacman
+- Internet access for package updates
+
+## Security
+
+The script:
+- Always asks for permission before installation
+- Uses official package repositories
+- Does not modify system files without permission
+- Can be safely interrupted at any time (Ctrl+C)
+
+## Troubleshooting
+
+### Script cannot find Python after installation
+Restart your terminal or run:
+```bash
+source ~/.bashrc  # for bash
+source ~/.zshrc   # for zsh
+```
+
+### Permission errors
+Make sure you have sudo privileges and your user can install packages.
+
+### Homebrew not found (macOS)
+Install Homebrew:
+```bash
+/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
+```
+
+## Script Features
+
+- **Multi-platform support**: Works on macOS, Ubuntu/Debian, and Arch Linux
+- **Smart detection**: Checks multiple Python command variants (python3.12, python3.13, python3, python)
+- **Safe installation**: Always prompts before making changes
+- **Colored output**: Easy-to-read status messages
+- **Error handling**: Graceful handling of edge cases and errors
+- **Verification**: Post-installation verification to ensure success
