This method allows you to filter the dictionary items based on a condition and then extract the keys. Here’s how to implement it: def find_key_by_value_filter(d, target_value): filtered_keys = filter(lambda item: item[1] == target_value, d.items()) return [key for key, value ...
findatapy includes an in-memory caching mechanism, which uses Redis a key/value in-memory store. The idea is that if we do exactly the same data download call with the same parameters of a MarketDataRequest it will check this volatile cache first, before going out to our external data pro...
