Retrieve choosen value of a ttk.combobox

Question

I am creating a user interface where there is a first window that ask the user to choose a parameter within a list of choices. Here is an MWE :

from tkinter import *
import tkinter.ttk as ttk

Port=''
root = Tk()

PortCOM = ttk.Combobox(root, values=[1,2,3,4,5,6])
PortCOM.bind("<<ComboboxSelected>>",Port)
PortCOM.pack ()

root.mainloop()

print(Port)

So i already tried that but also :

Port = PortCOM.get
Port = PortCOM.cget

With that last try, i get that error message :

<bound method Misc.cget of <tkinter.ttk.Combobox object .!combobox>>

For example, if the user choose the value '4' in my list of values, i want it to be stored in the variable 'Port'.

And if you don't want extra button you can just do this

from tkinter import *
import tkinter.ttk as ttk

Port=''
root = Tk()

def set_port(_):
    global Port
    Port = PortCOM.get()
    print(Port)

PortCOM = ttk.Combobox(root, values=[1,2,3,4,5,6])
PortCOM.bind("<<ComboboxSelected>>", set_port)
PortCOM.pack ()

root.mainloop()
