Is it possible to scan for Wi-Fi using Python?

Yes, it is possible. As far as the how is concerned, this might help you get started.

Additionally you can use the pywifi package to scan for all wireless devices in your area.

example:

 import pywifi
 import time

 wifi = pywifi.PyWiFi()
 iface = wifi.interfaces()[0]
 iface.scan()
 time.sleep(0.5)
 results = iface.scan_results()


 for i in results:
     bssid = i.bssid
     ssid  = i.ssid
     print(f"{bssid}: {ssid}")
