- pickle - Understanding Pickling in Python - Stack Overflow
The pickle module implements a fundamental, but powerful algorithm for serializing and de-serializing a Python object structure Pickling - is the process whereby a Python object hierarchy is converted into a byte stream, and Unpickling - is the inverse operation, whereby a byte stream is converted back into an object hierarchy Pickling (and unpickling) is alternatively known as serialization
- Using pickle. dump - TypeError: must be str, not bytes
0 pickle uses a binary protocol, hence only accepts binary files As said in the first sentence, "The pickle module implements binary protocols for serializing and de-serializing"
- What difference between pickle and _pickle in python 3?
The pickle module already imports _pickle if available It is the C-optimized version of the pickle module, and is used transparently From the pickle py source code: # Use the faster _pickle if possible try: from _pickle import * except ImportError: Pickler, Unpickler = _Pickler, _Unpickler and from the pickle module documentation: The pickle module has an transparent optimizer (_pickle
- Saving and loading objects and using pickle - Stack Overflow
It seems you want to save your class instances across sessions, and using pickle is a decent way to do this However, there's a package called klepto that abstracts the saving of objects to a dictionary interface, so you can choose to pickle objects and save them to a file (as shown below), or pickle the objects and save them to a database, or

- Python pickle protocol choice? - Stack Overflow
pickle dump(d, pfile, protocol=pickle HIGHEST_PROTOCOL) pickle HIGHEST_PROTOCOL will always be the right version for the current Python version Because this is a binary format, make sure to use 'wb' as the file mode! Python 3 no longer distinguishes between cPickle and pickle, always use pickle when using Python 3
- How can I use pickle to save a dict (or any other Python object)?
