AccessGatewayFilter question

[xingjianll]

In AccessGatewayFilter skeleton, there is this method:

def is_start_with(self, request_uri):
        """
        Check if the request URI starts with certain prefixes.
        :param request_uri: str, the URI of the request
        :return: bool, True if the URI starts with certain prefixes, False otherwise
        >>> filter = AccessGatewayFilter()
        >>> filter.is_start_with('/api/data')
        True

        """

the solution is as below:

def is_start_with(self, request_uri):
    start_with = ["/api", '/login']
    for s in start_with:
        if request_uri.startswith(s):
            return True
    return False

how is it possible that the llm would infer "/api", '/login' are the only possible prefixes, based on the function docstring?
