pickle.load() vs pickle.dumps()
pickle.load() and pickle.dumps() are both Python Pickle Module APIs, and choosing between them is a common point of confusion. This page compares their syntax, parameters, return values, and typical use cases so you can pick the right one. pickle.load(): Deserializes a Python object from a pickle file. Its syntax is pickle.load(file, *, fix_imports=True, encoding="ASCII", errors="strict"), and it returns deserialized object pickle.dumps(): Serializes a Python object to bytes (instead of file). Its syntax is pickle.dumps(obj, protocol=None, *, fix_imports=True), and it returns bytes Example of pickle.load(): with open("data.pkl", "rb") as f:
data = pickle.load(f)
# data = {"key": [1,2,3]}. Example of pickle.dumps(): data = pickle.dumps({"key": [1,2,3]})
type(data) # bytes. Read the full references for pickle.load() and pickle.dumps() to see parameters, edge cases, and example code side by side. Other Pickle Module APIs worth comparing: pickle.dump(), pickle.loads(), pickle.HIGHEST_PROTOCOL. Both belong to the Pickle Module category in the Python Reference documentation.
