Running commands based on OptionMenu's selection

If you want to run specific methods for options, simply check the sent string and select the method based on the string using if / elif statements:

from tkinter import *def xyz17():    print('xyz17')def abc27():    print('abc27')def qwe90():    print('qwe90')def uio19():    print('uio19')def jkl09():    print('jkl09')def zxc28():    print('zxc28')class Menu(OptionMenu):    def __init__(self, master, status, *options):        self.var = StringVar(master)        self.var.set(status)        OptionMenu.__init__(self, master, self.var, *options, command=self.option_handle)    def option_handle(self, selected):        # above specific case is simply print(selected) but        if selected == "xyz17":            xyz17()        elif selected == "abc27":            abc27()        elif selected == "qwe90":            qwe90()        elif selected == "uio19":            uio19()        elif selected == "jkl09":            jkl09()        elif selected == "zxc28":            zxc28()        # if you specifically want to call methods that has exactly        # the same name as options        # eval(selected + "()")def main():            TopFrame = Frame(root)    TopFrame.pack()    Menu1 = Menu(TopFrame, 'xyz', 'xyz17','abc27','qwe90')    Menu2 = Menu(TopFrame, 'uio', 'uio19','jkl09','zxc28')    Menu1.pack()    Menu2.pack()root = Tk()main()root.mainloop()

One way of running a command based on the option menu selection is to use a dictionary of functions: func_dict = {option: function, ...} and then pass the following function to the command option of the OptionMenu:

def func(value):    func_dict[value]() 

to execute the function corresponding to the chosen option.

Here is an example:

from tkinter import *options = ['xyz', 'xyz17', 'abc27', 'qwe90', 'uio', 'uio19', 'jkl09', 'zxc28']func_dict = {option: lambda opt=option: print(opt) for option in options}class Menu(OptionMenu):    def __init__(self, master, status, *options):        self.var = StringVar(master)        self.var.set(status)        OptionMenu.__init__(self, master, self.var, *options, command=self.func)    def func(self, option):        func_dict[option]()def main():            topFrame = Frame(root)    topFrame.pack()    menu1 = Menu(topFrame, 'xyz', 'xyz17','abc27','qwe90')    menu2 = Menu(topFrame, 'uio', 'uio19','jkl09','zxc28')    menu1.pack()    menu2.pack()root = Tk()main()root.mainloop()
