Child Table Update

I use self.append(‘child table name’,{}) to add new row to the child table. What method should I use to update an existing row in the child table?

If you want to edit row #3:

self.child_table_name[2].to_change_value = value

Thanks @rmehta . Before I saw this, I solved it by looping through the children using -

    children = self.get_all_children()
    for d in children:

Your solution is more elegant.
