Why identical arguments can create different entries in `lru_cache`? 🤔 The lru_cache creates a key not only from the values of the arguments, but also from the way they are passed. load(True) load(debug=True) Although both calls pass the same value, for the cache, these are different keys, so the function will be executed twice. print(load.cache_info()) # CacheInfo(hits=0, misses=2, ...) The order of named arguments can also affect how an entry is created in the cache. func(a=1, b=2) func(b=2, a=1) Therefore, it is best to call cached functions in a consistent style: either by position or by name, in the same order. load(debug=True) load(debug=True) 🔥 A consistent call format prevents unnecessary cache misses and redundant execution of expensive operations. #Python #lru_cache #Caching #Performance #ProgrammingTips #CodeBestPractices ✨ Join Best TG Channels https://t.me/addlist/0f6vfFbEMdAwODBk ⭐️ Join Our WhatsApp Channel https://whatsapp.com/channel/0029VaC7Weq29753hpcggW2A
