input: From the given instruction, the task is to create a function that validates a list of emails. Here's how you can properly define this function in Python, including the function header, comments with test cases, and expected outputs:
  
  
  import re
  
  def validate_mail_list(mail_list):
      """
      Validate a list of email addresses. Returns a boolean indicating whether all 
      email addresses in the list are valid.
      
      >>> validate_mail_list(["example.user@gmail.com", "good@domain.co"])
      True
      >>> validate_mail_list(["example.user@gmail.com", "bad@example"])
      False
      """
      for mail in mail_list:
          if not re.match("[^@]+@[^@]+\.[^@]+", mail):
              return False
      return True
  
  
  This function goes through each email in the `mail_list` and checks if it matches a standard email pattern using `re.match()`. If any email does not match the pattern, the function returns `False`. If all emails are valid, it returns `True`.
output:     for mail in mail_list:
          if not re.match("[^@]+@[^@]+\.[^@]+", mail):
              return False
      return True
