can't able to access entry textvariable(define in function) form main code in python tkinter

Question

Program: GUI form app in tkinter(using entry,button,tkinter)

Problem: can't get the value of entry field in main code from show() function

name.get() in submit() does not print any value in main code

Main code

if __name__ ==  '__main__':
window = Tk()
name = tk.StringVar()
def submit():
    print(name.get())
    print("inside submit")
Alpha(window)
window.title('Alpha Inventory System...!')
window.geometry('930x565')
window.mainloop()

Alpha init, here I call show() method(at 'item3' line) which further call submit method

def __init__(self,win):
   
    chooser = Menu()
    item1 = Menu(tearoff=0)
    item1.add_command(label='User Account details')
    item1.add_command(label='User persaonal details')
    
    item2 = Menu(tearoff=0)
    item2.add_command(label='Admin Account Details')
    item2.add_command(label='Admin Personal details')
    
    item3 = Menu(tearoff=0)
    item3.add_command(label='Add Customer',command=self.show)
    item3.add_command(label='Delete Customer',command=self.delete_cust)
    
    item4 = Menu(tearoff=0)
    item4.add_command(label='Add Product',command=self.addproduct)
    item4.add_command(label='Delete Product',command=self.delete)
    item4.add_command(label='Update Product',command=self.update)
    item4.add_command(label='View/Search Product')
    
    item5 = Menu(tearoff=0)
    item5.add_command(label='Generate order')

    
    item6 = Menu(tearoff=0)
    
    item7 = Menu(tearoff=0)
    item7.add_command(label='Exit',command=self.ExitApplication)
    
    
    chooser.add_cascade(label='User Profile',menu=item1)
    chooser.add_cascade(label='Admin Master',menu=item2)
    chooser.add_cascade(label='Customer Master',menu=item3)
    chooser.add_cascade(label='Product Master',menu=item4)
    chooser.add_cascade(label='Order Master',menu=item5)
    chooser.add_cascade(label='Report',menu=item6)
    chooser.add_cascade(label='Exit',menu=item7)
    
    win.config(menu=chooser)

show() method, here I set textvariable=name in "tk.Entry" method. It can't access form 'main_code' where I print it, name.get() is empty there

  text = tk.Entry(f1, textvariable=name,fg='blue', bg='lightyellow')
