val_1 = ['a', 'b', 'c']
val_2 = ['A', 'B', 'C']

You can use a while statement until you get a number out of your
excluded numbers
excludedNumbers = [1,2,3,4]
randomNumber = random.randomint(1,100)
while randomNumber in excludedNumbers:
randomNumber = random.randomint(1,100)
After the while you have a number outside the excluded nu
