getting selected value of Combobox python

Hi I have the following code 

def create(self):
    geo = StringVar()
    city = ttk.Combobox(gui, textvariable=geo,state="readonly")
    city.config(values=self.geo)
    city.pack()
    city.bind("<<ComboboxSelected>>", self.cityselection)


def cityselection(self,event):
    selected=event
    print(selected)

I want to send the selected value of from the Combobox to cityselection function but when I print it I only get

VirtualEvent event x=0 y=0

and it does not matter which value I choose I will always get the above output instate of for e.g: London or Toronto,

this worked for me :

def create(self):
        print(self.geo)
        strgeo="\n".join(str(x) for x in self.geo)

        print(strgeo)
        city = ttk.Combobox(gui, textvariable=self.stringGeo, state="readonly",width=30)
        city.config(values=strgeo)
        city.pack()
        city.bind("<<ComboboxSelected>>",self.selectedCity)

    def selectedCity(self,event):
        selected=self.stringGeo.get()

As it stands you cannot retrieve the value of geo, since it is not defined as an attribute of your class, but in the local scope of create. What you can do is declaring geo as a static attribute and then call it from within your method when you need it.

class(object):

    geo = StringVar()
    geos = ('NY','LA','RY','...')

    def __init__(self,#....
        #...

    def create(self):
        city = ttk.Combobox(gui, textvariable=self.geo,state="readonly")
        city.config(values=self.geos) 
        city.pack()
        city.bind("<<ComboboxSelected>>", self.cityselection)


    def cityselection(self,event):
        selected=self.geo.get()
        print(selected)

Actually, event is not what you think it is.
