-

this question has answer here:

so i'm working on, again code in this question...
im wondering how go doing this: 

from tkinter import * tkinter import messagebox mb # ... def info(text):     mb.showinfo(text) # ... helpmenu.add_command(label="version", command=info("not yet realesed")) # ...

what automaticly executes info().
how can prevent this?

you need use lambda function prevent info() being executed automatically:

helpmenu.add_command(label="version", command=lambda: info("not yet realesed"))
