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 ...
I have looked through the information that the Python documentation for pickle gives, but I'm still a little confused. What would be some sample code that would write a new file and then use pickle...
How can I use pickle to save a dict (or any other Python object)?
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 ...
The following is an example of how you might write and read a pickle file. Note that if you keep appending pickle data to the file, you will need to continue reading from the file until you find what you want or an exception is generated by reaching the end of the file. That is what the last function does.
Pickle is unsafe because it constructs arbitrary Python objects by invoking arbitrary functions. However, this is also gives it the power to serialize almost any Python object, without any boilerplate or even white-/black-listing (in the common case).

Python multiprocessing PicklingError: Can't pickleare you asking for why would I need Pickle for serialization in Python? or rather what is (the purpose of) serialization after all?.
Using pickle is same across all machine learning models irrespective of type i.e. clustering, regression etc. To save your model in dump is used where 'wb' means write binary.
Thus, to pickle a list, pickle will start to pickle the containing list, then pickle the first element… diving into the first element and pickling dependencies and sub-elements until the first element is serialized.
