How do I iterate a random generator in Tkinter? - Python

I have a basic GUI for my app using Tkinter, the generator will show me a random word from the dictionary in Hebrew, there are two main functionalities I do not know how to create.

1) When I click next, I want to see a new vocabulary word. How do I create a function to generate a new word in the designated Tkinter frame when I click the 'next' button?

2) When I click submit, I want to check if the English (key) matches the Hebrew (value) in my dictionary. How do I create a function to verify the user input against the corresponding key to the given value for the button command?

I'm new, so appreciate the learning opportunity, and I actually want to use this app for my own studying. Here is most of the code:

dictionary = {'give her':'תנ לה', 'give me': 'תני לי', 'give us': 'תן לנו' ,'give him': 'תן לו', 'give them': 'תן להם' , 'give to them (f)': 'תן להן'}

question = random.choice(list(dictionary.values()))

answer = dictionary.keys() == question
