Python, often referred to as a “glue language”, is a versatile programming language that seamlessly integrates and interacts with different components. It’s like a universal translator, bridging the gap between various software components, each written in its own language.
This unique ability stems from Python’s clear syntax, dynamic typing, and interpreted nature, which make it an ideal language for scripting and rapid application development in many areas on most platforms.
So, when you hear Python being called a “glue language”, it’s all about its power to bring other technologies together in a cohesive manner.
Python is often used as a glue language in various scenarios
Here are a few examples of python used as a glue language:
Cloud Development: Python is used as a glue language in cloud development to increase the reliability and dependability of development and operations practices. It's used to automate connectivity between components, making it easier to manage and operate cloud services.
Scripting Language: Python is used as a glue language to orchestrate modules written in different languages, making them work together to form an application. It's convenient syntax, good support for inter-process communication, and data munging capabilities make it an ideal choice for this purpose.
Connecting Software Components: Python is used as a glue language to connect software components. It can interface with OS commands, interfaces, DLLs, shared libraries, services, objects, etc., making it a versatile choice for integrating various software components.
Scientific Computing with NumPy: Python is used as a glue language in scientific computing with NumPy. It's used to compile extension modules, providing a seamless interface between Python and C/C++ libraries.

Why Python is called interpreted language?
Python is often referred to as an interpreted language because it executes code directly, line by line, without the need for explicit compilation into machine language. When a Python program is run, it is processed by the interpreter, which reads and executes the code statements one by one.
However, it's important to note that Python is both compiled and interpreted. This means when we run a Python code, it is first compiled and then interpreted line by line. The compilation part is mostly hidden from the user. While running the code, Python generates a byte code internally, this byte code is then converted using a python virtual machine (p.v.m) to generate the output.
The interpreter also performs error checking during the execution of the code. If an error is found in a particular line, the interpreter will halt the program and report the error. This characteristic makes debugging easier as it provides information about the source point of error.

Why is Python called CPython?
Python is often referred to as CPython to distinguish it from other implementations of the Python programming language. CPython is the original and most widely used implementation of Python. It's called CPython because it's written in C and Python.
CPython compiles Python code into bytecode before interpreting it. This means that CPython can be defined as both an interpreter and a compiler. The name "CPython" is used when you want to contrast it with other implementations of Python.

Why Python is called object oriented language?
Python is referred to as an object-oriented programming language because it uses a programming paradigm that centers on objects and classes. In Python, almost everything is an object, with its properties and methods.
Object-oriented programming (OOP) in Python aims to implement real-world entities like inheritance, polymorphism, and encapsulation. Here's a brief explanation of these terms:
- Inheritance allows us to define a class that inherits all the methods and properties from another class.
- Polymorphism allows us to use a single type entity (method, operator or object) to represent different types in different scenarios.
- Encapsulation is the practice of keeping fields within a class private, then providing access to them via public methods.
These features make Python a powerful tool for creating complex software in a more manageable way. It's also worth noting that Python supports other programming paradigms as well, including procedural and functional programming.
What are some other programming paradigms supported by Python?
Python supports several programming paradigms, including:
- Object-Oriented Programming (OOP): In this paradigm, objects are the key elements. Objects can be defined as instances of a class that contain both data members and method functions.
- Procedural Programming: This paradigm involves writing code in functions, which are then executed sequentially. It helps in the modularity of code and each file acts as a container.
- Functional Programming: This paradigm is based on pure mathematical functions. It allows you to write code that is more readable, testable, and coherent.
- Imperative Programming: This paradigm involves giving the computer a sequence of tasks, which it then carries out. This makes it easier to follow the flow of the program.
Each of these paradigms has its own advantages and disadvantages, and Python's flexibility allows developers to choose the one that best suits their needs for a particular task.
