Using pickletools.dis() to analyze serialized data. 🐍 pickle doesn't just store a snapshot of an object; it stores a sequence of instructions for its subsequent reconstruction. Normally, we only see the result of serialization: import pickle payload = pickle.dumps( {"name": "Alex", "roles": ["admin", "user"]} ) print(len(payload)) The standard library includes pickletools.dis(), which disassembles the pickle stream and shows its instructions in a readable format. import pickletools pickletools.dis(payload) The output shows the creation of a dictionary, strings, a list, and the operations used to assemble the final object. EMPTY_DICT SHORT_BINUNICODE 'name' SHORT_BINUNICODE 'Alex' SHORT_BINUNICODE 'roles' EMPTY_LIST This is useful when debugging your own classes: you can check which global objects and reconstruction mechanisms are included in the serialization. class User: def init(self, name): self.name = name payload = pickle.dumps(User("Alex")) pickletools.dis(payload) For further analysis, there's pickletools.optimize(): it removes some unused operations from the pickle stream without changing the object being reconstructed. optimized = pickletools.optimize(payload) assert pickle.loads(optimized).name == "Alex" ⚠️ pickletools is designed for analyzing pickle streams, not for safely reading untrusted data. You should still not pass unknown pickle data to pickle.loads(). 🔥 pickletools.dis() allows you to peek inside the serialization and see the instructions from which pickle reconstructs the object. #Python #Pickle #DataScience #Debugging #Coding #DevTools ✨ Join Best TG Channels https://t.me/addlist/0f6vfFbEMdAwODBk ⭐️ Join Our WhatsApp Channel https://whatsapp.com/channel/0029VaC7Weq29753hpcggW2A
