List All Wireless Networks Python for PC

This is a question from the olden days, but even at the time the accepted answer could have been much more Pythonic - e.g.,

r = subprocess.run(["netsh", "wlan", "show", "network"], capture_output=True, text=True).stdout
ls = r.split("\n")
ssids = [k for k in ls if 'SSID' in k]

If you just want to SSID names in a list, change the ssids = line to

ssids = [v.strip() for k,v in (p.split(':') for p in ls if 'SSID' in p)]

You'll want the subprocess module and a windows command:

import subprocess
results = subprocess.check_output(["netsh", "wlan", "show", "network"])

A little extra to just get SSID's.

results = results.decode("ascii") # needed in python 3
results = results.replace("\r","")
ls = results.split("\n")
ls = ls[4:]
ssids = []
x = 0
while x < len(ls):
    if x % 5 == 0:
        ssids.append(ls[x])
    x += 1
print(ssids)
