import tkinter as tk
import random
root=tk.Tk()
def rand():

    animalist1=['dog','cat','cow','horse','duck','bird']
    animalist2 = ['Hippo', 'Bat', 'Fish', 'Whale', 'Bear', 'Monkey']

    seqs = [animalist1,animalist2]
    animalrand1 = random.choice(random.choices(seqs, weights=map(len, seqs))[0])


    #animalrand1 = random.choice(animalist1)
    #animalrand2 = random.choice(animalist2)
    label.configure(text=animalrand1)
    #label.configure(text=animalrand2)
