How do I get Tkinter Entry.get() to equal 0 if theres no entry?

Question

Im writing a restaraunt management program in tkinter and I have the menu listed out. if I don't put anything in the entry box it will say error. How do I make it that when the entry box is empty, it is equal to 0?

Answer 1

You can assign a value like this:

value = entry.get() or 0

If the entry widget has nothing in it, it will return an empty string. An empty string is treated as False in an expression. Because it is False, the part after the or will be returned.
