I wrote the below code

    prev_leaf = [None]
    _AnnotateIndents(tree)
    def _VisitNodeRec(node):
        for child in node.children[:]:
            if isinstance(child, pytree.Node):
                _VisitNodeRec(child)
            else:
                if child.prefix.lstrip().startswith('#'):
                    comment_prefix = child.prefix
                    comment_lineno = (child.lineno - comment_prefix.count('\n'))
                    comment_column = child.column
                    child_prefix = child.prefix.lstrip('\n')
                    prefix_indent = child_prefix[:child_prefix.find('#')]
                    if ('\n' in prefix_indent):
                        prefix_indent = prefix_indent[(prefix_indent.rfind('\n') + 1):]
                    child.prefix = ''
                    if (child.type == token.NEWLINE):
                        comment_column -= len(comment_prefix)
                        comment_column += (len(comment_prefix) - len(comment_prefix.lstrip()))
                        pytree_utils.InsertNodesAfter(_CreateCommentsFromPrefix(comment_prefix, comment_lineno, comment_column, standalone=False), prev_leaf[0])
                    elif (child.type == token.DEDENT):
                        ancestor_at_indent = _FindAncestorAtIndent(child, prefix_indent)
                        if (ancestor_at_indent.type == token.DEDENT):
                            comments = comment_prefix.split('\n')
                            before = []
                            after = []
                            after_lineno = comment_lineno
                            index = 0
                            while (index < len(comments)):
                                cmt = comments[index]
                                if ((not cmt.strip()) or cmt.startswith((prefix_indent + '#'))):
                                    before.append(cmt)
                                else:
                                    after_lineno += index
                                    after.extend(comments[index:])
                     ...

What's a good function header?
