Disable submit button until all fields are filled in Python Tkinter

I'm currently working on a project and when my program launches it needs to get the names off of two players before beginning, the way my program is at the moment, it is possible to press submit without entering names, how do I prevent this?

Many Thanks Jayode18

You can check the entry texts for example

if entry1.get() != "" And entry2.get() != "":
    # entries are not empty, do something
