Problem with the python Random function

Question

Hello I have a typeErro problem. but I don’t know what can be, I’m beginner in python

import random 
def ataque(bonus, defesa, dano, bonus_dano):
    dano_total = [(random.randint(1, dano)+bonus_dano) for i in range(1)]
    ataque_total = [(random.randint(1, 20)) for i in range(1)]
    dano_critico = [(random.randint(1, dano)+2*bonus_dano) for i in range(2)]
    total_dano_critico=sum(dano_critico)

    if ataque_total == 20 and ataque_total + bonus_dano >= defesa:
        print(total_dano_critico)
    else:
        if ataque_total+bonus_dano >= defesa :
          print(dano_total)
        else:
          print("errou")
