Python serialize object to binary
MPI for Python
We are going to use the in-built pickle module to serialize and de-serialize complex objects like a dictionary or a class object for writing and reading from a file. the pickle.dump() and pickle.load() functions will be used for this. In the following example we are going to write and read a dictionary as it is into a binary file. In [68 ...

How to serialize object, list and dictionary in Python with Examples
Serialization is converting the object in binary format and being able to store it in a storage medium. Many programming languages provide interfaces for serializing which can be implemented by our object classes that we want to serialize. Serialization and deserialization can hence be

Deserialization 101 •Deserialization is the same but in reverse ☺ •Taking a written set of data and read it into an object •There are “deserialization” not “serialization” vulnerabilities because objects in memory are usually safe for serialization. Users however can provide malicious data for deserialization.

Python code can be distributed in binary form by utilizing the marshal module [3]. This module provides the ability to serialize and deserialize code objects using the store and load functions. The most commonly encountered binary format is a compiled Python file (.pyc) which contains a magic number, a timestamp, and a serialized object.
MPI for Python
The Python standard library supports different mechanisms for data persistence. Many of them rely on disk storage, but pickling and marshaling can also work with memory buffers. The picklemodules provide user-extensible facilities to serialize general Python objects using ASCII or binary formats.

to serialize built-in Python objects using a binary format specific to Python, but independent of machine architecture issues. MPI for Python can communicate any built-in or user-defined Python object taking advantage of the features pro-vided by the mod:pickle module.
