How to access a variable defined inside a function, from outside that function
<p>I am stuck on using variables defined in a previous function in another function. For example, I have this code:</p>

<pre><code>def get_two_nums():
    ...
    ...
    op = ...
    num1 = ...
    num2 = ...
    answer = ...

def question():
    response = int(input("What is {} {} {}? ".format(num1, op, num2)))
    if response == answer:
        .....
</code></pre>

<p>How will I use the variables defined in the first function in the second function? Thank you in advance</p>
