can't find the solution for warrior.py

I can't get the script to work. It falls into an error every time I run it, despite I think it shouldn't. My code is attached.

warrior.py 
from character import Character;
class Warrior(Character):
  pass

  def __init__(self):
    self.weapon = 'sword';

  def rage(self):
    self.attack_limit = 20;

  def __str__(self):
    cadena = "Warrior, <" + self.weapon + ">, <" + self.attack_limit +">";
    return cadena;

There's a easier way of concatenation when you're inserting multiple values.

If the value is predefined, you can insert them via the .format() function.

  def __str__(self):
    return "Warrior, {}, {}".format(self.weapon, self.attack_limit)

note how these values will be inserted at the locations of the '{}' or curly brackets as they're commonly referred to. You can utilize this method as long as the variables are defined and everything is in proper order.

Think about what you were doing by declaring 'candena ='. Does your prior method allow for all the characters to utilize the __str__(self) function? And which version of the function is more useful?

The specific error your are getting caused by trying to concatenate an int with a string. Two choices:

1. Wrap the int in a str():

  def __str__(self):
    cadena = "Warrior, <" + self.weapon + ">, <" + str(self.attack_limit) +">";
    return cadena;

2. Use the format() method as suggested by Andrew.
