cambiar las variables del siguiente codigo al español function isValid(s) { const stack = []; const map = { '(': ')', '{': '}', '[': ']' }; for (let i = 0; i < s.length; i++) { let char = s[i]; if (map[char]) { stack.push(char); } else { let last = stack.pop(); if (map[last] !== char) { return false; } } } return stack.length === 0; }

Script
const map = {
    '(': ')',
    '{': '}',
    '[': ']'
  };

def is_valid(s):
  stack = []
  for char in s:
    if char in map:
      stack.append(char)
    else:
      last = stack.pop()
      if map[last] != char:
        return False
  return len(stack) == 0
