That's weired why is this working:
class web_sites_extra():
def servername( self ):
return self.web_sites.txt.split()
and this not:
class web_sites_extra():
def servername( self ):
r=self.web_sites.txt.split()
return self.web_sites.txt.split()
or this:
class web_sites_extra():
def servername( self ):
r="something"
return self.web_sites.txt.split()
