code in python, a tool that grabs WiFi information

Certainly! Below is an example of a simple Python script that retrieves WiFi information using the `subprocess` module to execute operating system commands. The implementation can vary based on the operating system (Windows, macOS, or Linux).

This example will cover the following platforms:
- Windows: Using `netsh`
- Linux: Using `nmcli`
- macOS: Using `airport`

### Python Script to Grab WiFi Information

```python
import subprocess
import platform
import json

def get_wifi_info():
    os_type = platform.system()

    if os_type == "Windows":
        return get_windows_wifi_info()
    elif os_type == "Linux":
        return get_linux_wifi_info()
    elif os_type == "Darwin":  # macOS
        return get_macos_wifi_info()
    else:
        raise NotImplementedError(f"OS '{os_type}' is not supported.")

def get_windows_wifi_info():
    try:
        result = subprocess.check_output("netsh wlan show interfaces", shell=True, text=True)
        return parse_windows_output(result)
    except subprocess.CalledProcessError:
        return {"error": "Failed to retrieve WiFi information"}

def parse_windows_output(output):
    info = {}
    lines = output.splitlines()
    for line in lines:
        if ":" in line:
            key, value = line.split(":", 1)
            info[key.strip()] = value.strip()
    return info

def get_linux_wifi_info():
    try:
        result = subprocess.check_output("nmcli dev wifi", shell=True, text=True)
        return parse_linux_output(result)
    except subprocess.CalledProcessError:
        return {"error": "Failed to retrieve WiFi information"}

def parse_linux_output(output):
    lines = output.strip().splitlines()
    if len(lines) < 2:
        return {"error": "No WiFi information available"}
    wifi_info = lines[1].split()
    return {
        "SSID": wifi_info[0],
        "Signal": wifi_info[2],
        "Security": wifi_info[3],
    }

def get_macos_wifi_info():
    try:
        result = subprocess.check_output("/System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -I", shell=True, text=True)
        return parse_macos_output(result)
    except subprocess.CalledProcessError:
        return {"error": "Failed to retrieve WiFi information"}

def parse_macos_output(output):
    info = {}
    lines = output.splitlines()
    for line in lines:
        if ":" in line:
            key, value = line.split(":", 1)
            info[key.strip()] = value.strip()
    return info

if __name__ == "__main__":
    wifi_info = get_wifi_info()
    print(json.dumps(wifi_info, indent=4))
```

### How to Use the Script
1. **Install Python**: Ensure that Python is installed on your system (Python 3.x is recommended).
2. **Run the Script**:
   - Save the code into a file, for example, `wifi_info.py`.
   - Open a terminal or command prompt.
   - Navigate to the folder where the script is saved.
   - Run the script with `python wifi_info.py`.

### Note
- **Windows**: Run the script as Administrator to avoid permission issues.
- **Linux**: Make sure you have `nmcli` installed (most distributions do).
- **macOS**: The airport tool is built-in and does not require installation.
- This script may need adjustments based on specific requirements or details you want to retrieve.
