I wrote the below code

    def is_flat_params(env_or_param):
        if (env_or_param is None):
            return False
        for sect in env_fmt.SECTIONS:
            if (sect in env_or_param):
                return False
        return True
    child_env = parent_env.user_env_as_dict()
    child_env[env_fmt.PARAMETERS] = {}
    flat_params = is_flat_params(child_params)
    new_env = Environment()
    if (flat_params and (child_params is not None)):
        child_env[env_fmt.PARAMETERS] = child_params
    new_env.load(child_env)
    if ((not flat_params) and (child_params is not None)):
        new_env.load(child_params)
    if (item_to_remove is not None):
        new_env.registry.remove_item(item_to_remove)
    if child_resource_name:
        new_env.registry.remove_resources_except(child_resource_name)
    return new_env

What's a good function header?

Here's a good function header?
