This def has too many IF, i don't know how to optimize this code for more simplier and professional.

Please take a look.

def cfg_wlan(self, wlan_cfg):


    Configure a new wlan for Zone Director.


    Input: a dictionary, supplied in

    Output: none



    if wlan_cfg['auth'] == "PSK":

I suggest this simpler code. Check that it works as you expect

def cfg_wlan(self, wlan_cfg):

    Configure a new wlan for Zone Director.

    Input: a dictionary, supplied in

    Output: none

    defaults = [
        ('ssid', None), ('auth', None),
        ('encryption', None), ('wpa_ver', None),
        ('key_string', None), ('key_index', None),
        ('auth_server', ""), ('use_web_auth', False),
        ('use_guest_access', False), ('acl_name', ""),
        ('use_hide_ssid', False), ('vlan_id', ""),
        ('uplink_rate_limit', ""), ('downlink_rate_limit', ""),
        ('use_client_isolation', False), ('use_zero_it', False),
        ('use_dynamic_psk', False), ('do_tunnel', False)
    argdict = dict([(k, wlan_cfg.get(k, v)) for (k, v) in defaults])

    if not 'use_zero_it' in wlan_cfg:
        argdict['use_dynamic_psk'] = False

    if argdict['auth'] == "PSK":
        argdict['auth'] = "open"
    if argdict['auth'] == "EAP":
        if wlan_cfg['use_radius']:
            argdict['auth_server'] = wlan_cfg['ras_addr']
    elif argdict['use_web_auth']:
        argdict['auth_server'] = wlan_cfg['ras_addr'] or wlan_cfg['ad_addr'] or ""
    args = [argdict[k] for (k, v) in defaults]
