[Tkinter] [python]Problem in creating menu[/python]

[Larz60+]

the open function can't be a string for it to execute it need to be a function pointer, it also needs to
somehow run menu.command, i tried the following, but it also does not work:

from tkinter import *
from tkinter import ttk
from tkinter import messagebox
from tkinter import filedialog
import numpy as np
 
 
class My_actions():
    def __init__(self):#, **kwds): 
        pass
    def open_file(self ):
        print('Trying to open')
        file_name = filedialog.askopenfilename(filetypes=(("PNG","*.png"),("Gif","*.gif"),("All files","*.*")))
        image_file = open(file_name).read()
        print(image_file)
 
    def all_menu(self, main_menu , all_menu_dict):
        #File menu
        for i,j in all_menu_dict.items():    
            main_menu.add_command( label = i,  command = lambda : j)
 
class My_frame(My_actions):#My_actions):
    def __init__(self, **kwds):
        super().__init__()
 
        self.file_menu_dict = {
            'Open' : self.open_file,
            'Save' : '',
            'Save as': '',
            'Print' : '',
            'Close' : '',
            'Exit'  : '',                            
        }

        #Menu frame start        
        self.menu_frame = LabelFrame(kwds['root'] )
        self.menu_frame.background = 'red'
        self.menu_frame.grid(row = 2, column = 0, columnspan=4, sticky= kwds['sticky'])#side  = menu_side)
                 
        #Menu frame end
         
    def all_menu_frame(self, root):
            #menu start here
            menubar = Menu(self.menu_frame)
            file = Menu(menubar)
             
            menubar.add_cascade(menu=file, label="File")
            root.config(menu = menubar)
             
            # Method to call file menu
            self.all_menu(file, self.file_menu_dict)
            
 
            #menu end here
#Class my frame for both menu & status menu  end here
 
def main():
    root = Tk()
    window_size_x=0
    window_size_y=0
         
    root.geometry("%dx%d+%d+%d" %(root.winfo_screenwidth(), root.winfo_screenheight(), window_size_x, window_size_y))
     
    actions = My_frame( root=root, frame_width=400, frame_height =50, sticky='S')    
    actions.all_menu_frame(root = root)
     
    root.mainloop()


if __name__ == '__main__' :
    main()

However this does:

        image_file = open(file_name).read()
        print(image_file)
 
    def save_file(self):
        pass
    def save_as_file(self):
        pass

        pass
