How Can I Request UAC Elevation for My Python Script?

Requesting UAC Elevation in a Python Script

When executing Python scripts that require administrative privileges, it's necessary to handle User Account Control (UAC) in order to gain the required permissions. Here's how:

Method:

Python 2.x:

import ctypes, sys

def is_admin():
    try:
        return ctypes.windll.shell32.IsUserAnAdmin()
    except:
        return False

if is_admin():
    # Code of your program here
else:
    # Re-run the program with admin rights
    ctypes.windll.shell32.ShellExecuteW(None, u"runas", unicode(sys.executable), unicode(" ".join(sys.argv)), None, 1)

For Python 3.x, replace the last line with:

ctypes.windll.shell32.ShellExecuteW(None, "runas", sys.executable, " ".join(sys.argv), None, 1)

Advantages:

• No external libraries required (uses ctypes and sys from standard library)
• Works on both Python 2 and Python 3
• No modifications to file resources or manifest files required
• Prevents unnecessary code execution by not running within the if/else block
• Allows for the retrieval of the API call return value to take action if it fails
