Is there a way to get a random value from a Python dictionary and find a value from another dictionary using it?

I'm trying to make a system where I take a value from a dictionary, and then attempt to find a value from a different dictionary with it. I've attempted this multiple times and have not been successful.

import random

dic = {
        '1': 'hi',
        '2': 'hi2',
    }
dic2 = {
        '1': 'hello',
        '2': 'hello2',
}

x = random.choice(list(dic))
print(x)
y = dic2['x']
print(y)

This code is non-funcitonal and returns File "<PATH>", line 16, in <module> <y = dic2['x'] KeyError: 'x'
