The Pickle dump() and dumps() functions are used to serialize an object. The only difference between them is that dump() writes the data to a file, while dumps() represents it as a byte object. Similarly, load() reads pickled objects from a file, whereas loads() deserializes them ...
Suppose we want to design an algorithm to serialize and deserialize a binary search tree. Serialization is the process of converting something (data structure or object) into a sequence of bits so that it can be stored in a file or memory buffer, or transmitted across a network connection lin...

Serialize Other Python Data Types to JSONThe json module allows you to convert common Python data types to JSON. Here’s an overview of all Python data types and values that you can convert to JSON values:PythonJSON dict object list array tuple array str string int number float number True...
You can also serialize to a bytes object in memory. >>> shell 1 >>> b = pickle.dumps(entry) ① >>> type(b) ② <class 'bytes'> >>> entry3 = pickle.loads(b) ③ >>> entry3 == entry ④ TrueThe pickle.dumps() function (note the 's' at the end of the function name) ...

It converts python objects into sequence of binary data and vice versa and objects are said to be pickled or un-pickled accordingly. In this paper we have discussed how to serialize and de-serialize Python objects using Pickle module.Rakshith C A...
