Python is a high-level, interpreted, general-purpose programming language.

Key data types are integers, floats (real numbers), and strings.

List and array are container data types to store a large amount of data.

The for statement is useful to repeat actions by looping over a list of values.

The if – elif – else construct allows program to execute commands conditionally.

There are vast number of libraries which makes Python a productive computing platform.

You can use phe.paillier Python module to encrypt and decrypt images using Paillier Homomorphic Encryption.

Some implementations of FHE include Microsoft SEAL, PALISADE, and IBM

Homomorphic encryption can be used to perform machine learning or compute aggregates without revealing private data.
