Solve the following python programming problem given the following code:
def doMode(self, msg) : 
    def getSet(c) : 
        if (c == 'o') : 
            Set = self.ops 
else : 
            if (c == 'v') : 
                Set = self.voices 
else : 
                if (c == 'h') : 
                    Set = self.halfops 
else : 
                    if (c == 'b') : 
                        Set = self.bans 
else : 
                        Set = set () 
return Set 
for (mode, value) in ircutils.separateModes (msg.args [1 :]) : 
        (action, modeChar) = mode 
        if (modeChar in 'ovhbeq') : 
            Set = getSet (modeChar) 
            if (action == '-') : 
                Set.discard (value) 
else : 
                if (modeChar == '+') : 
                    Set.add (value) 
else : 
            if (action == '+') : 
                self.setMode (modeChar, value) 
else : 
                assert (action == '-') 
                self.unsetMode (modeChar)
