The path of the module is incorrect. Here in this dictionary, we have taken the number of states and their ranking worldwide as the data. Items that expire because they have exceeded their time-to-live will be no longer accessible, and will be removed eventually. class AbstractDataSet (abc. session["DISCORD_OAUTH2_TOKEN"] = token. The default is to call cachetools.keys.hashkey (). If lock is not None, it must specify an object implementing the context manager protocol. Any access to the cache will then be nested in a with lock: statement. What is in this value is not relevant, but it is used for the next method cas call. Funding Cerberus¶. 2.
