Python dictionary key is not identified

Question

I have a method like following,

@staticmethod
def get_repo(tenant_id):
    """

    :param int tenant_id:
    :return: GitRepository object
    :rtype: GitRepository
    """
    AgentGitHandler.log.info(AgentGitHandler.__git_repositories)
    AgentGitHandler.log.info("Tenant ID %s" %tenant_id)
    for key,value in AgentGitHandler.__git_repositories.iteritems():
            if tenant_id == key:
                    AgentGitHandler.log.info("Key Matching")
                    AgentGitHandler.log.info(AgentGitHandler.__git_repositories[key])
            AgentGitHandler.log.info("Key %s : value %s ", key,value)
    if tenant_id in AgentGitHandler.__git_repositories:
        return AgentGitHandler.__git_repositories[tenant_id]
    AgentGitHandler.log.info("False condition")
    return None

I am trying to get call the above function like following,

git_repo = AgentGitHandler.get_repo(tenant_id)
git_repo.scheduled_update_task.terminate()

tenant_id parameter value is -1234 which is in the dictionary as a key. But I am getting a response like below.

AttributeError: 'NoneType' object has no attribute 'scheduled_update_task'

Why is the if condition getting false ?

Answer 1

You say in the doc string that tenant_id is an int, and it appears to be one in your log, but your dictionary key is a unicode string, -1234 != u'-1234'.
