code: def Columns(iterable):
    
    columns = sorted(iterable)
    return "({})".format(", ".join("`{}`".format(col) for col in columns))
docs: Returns a string of column names for MySQL INSERTs.
  
    To account for Iterables with undefined order (dicts before Python 3.6),
    this function sorts column names.
  
    Examples:
      >>> Columns({"password": "foo", "name": "bar"})
      u'(`name`, `password`)'
  
    Args:
      iterable: The iterable of strings to be used as column names.
    Returns: A string containing a tuple of sorted comma-separated column names.
