Introduction to Python Programming:
Guido van Rossum created Python, an interpreted, high-level, general-purpose programming language, in the 1980s. Its syntax and semantics are intended to be as concise and easy to read as possible while retaining powerful programming capabilities. Python is popular among software engineers because of its readability, robustness, and simplicity.
Python is a popular high-level, interpreted programming language that emphasizes readability and code reuse. It includes a number of features that make programming easier, such as support for data structures and Unicode.
Who Introduced Python Language?
Guido van Rossum at Centrum Wiskunde and Informatica (CWI) in the Netherlands conceived Python in the late 1980s as a successor to the ABC programming language, which was inspired by SETL and capable of exception handling and interfacing with the Amoeba operating system.
definition of Python programming:
Guido van Rossum created Python, an interpreted, object-oriented, high-level programming language with dynamic semantics. It was first released in 1991. The name "Python" is a nod to the British comedy group Monty Python and is intended to be simple as well as entertaining.

Different Fields where Python Programming is Used?
Python is used in a wide range of applications, including scientific computing, web development, data analysis, and software engineering. It outperforms most other languages in terms of readability and maintainability, making it a popular choice for scripting and small programming projects. Furthermore, its widespread availability on various platforms makes it simple to deploy across a wide range of systems. It is also used in finance and business, among other things. It has a flexible syntax that allows you to write code that is both readable and efficient.
What are the 13 features of Python?
Python is a general-purpose programming language that is interpreted and object-oriented. It has a redline library and a standard library, both of which provide many fundamental functions such as string manipulation, data access, and computation. Python also has a large developer community that contributes extensions to the language.

Advantages of Python Programming:
- Easy to Read, Learn and Write
Python is a high-level programming language with syntax similar to English. This makes the code easier to read and comprehend. Python is extremely simple to pick up and learn, which is why many people recommend it to beginners. In comparison to other major languages such as C/C++ and Java, you need fewer lines of code to perform the same task.
- Improved Productivity
Python is a very productive programming language. Because Python is so simple, developers can concentrate on solving the problem. They don't have to spend a lot of time learning the syntax or behaviour of the programming language. You write less code and accomplish more.
- Interpreted Language
Python is an interpreted language, which means that the code is executed line by line. In the event of an error, it suspends further execution and reports the error. Even if the program contains multiple errors, Python displays only one. This facilitates debugging.
- Dynamically Typed
Python does not know the type of variable until the code is executed. During execution, it assigns the data type automatically. Furthermore, the programmer is not required to declare variables and their data types.
- Free and Open-Source
Python is distributed under an OSI-approved open-source licence. As a result, it is free to use and distribute. You can download the source code, modify it, and even distribute your own Python version. This is beneficial for organisations that want to change a specific behaviour while also using their version for development.
- Vast Libraries Support
Python's standard library is vast; you can find almost any function required for your task. As a result, you do not need to rely on third-party libraries. Even if you don't, a Python package manager (pip) makes it easier to import other fantastic packages from the Python package index (PyPi). It also includes over 200,000 packages.
Many programming languages, such as C/C++, require you to change your code in order to run the programme on different platforms. Python is not the same as that. You only need to write it once and then run it anywhere.
What is OOPs in Python?
"OOP" in Python stands for "object-oriented programming." OOP is a programming paradigm that focuses on the creation of modular and reusable code. The acronym OOPs in Python stands for object-oriented programming. OOPs are also a method of structuring your code to make it easier to read and maintain. They also make your code more modular, making specific pieces of code easier to find and use.
What are the Three Scopes in Python?
Python has three scopes: local, global, and module. The current block of code is referred to as local scope, the current interpreter or process is referred to as global scope, and module scope refers to all modules imported by the current script.
- Local Scope
Variables defined in the function are variables with a local scope. The function body defines these variables. Let's look at an example to better understand this concept. In Example 1, we only used one variable, num. Because Num = 0 is defined outside the function, it is not a local variable. According to our definition, variables declared within the function body are considered local variables. Furthermore, num=1 is a local variable declared and printed within the function demo. The output of running this code is shown below.
- Global Scope
A global scope variable is one that can be read from anywhere in the programme. These variables are accessible both inside and outside of the function. Finally, if we want to use the same variable throughout the programme, we declare it as global.
- Module Scope
The term "scope" refers to a variable's or named module's ability to be seen by calling code. For instance, two modules may both declare the variable "X."
What Jobs Can You Do By Learning Python?
Some of the prominent job roles that you can apply for by honing your Python programming skills include:
- Software Engineer
- Python Developer
- Research Analyst
- Data Analyst
- Data Scientist
- Software Developer
Furthermore, the high-paying job opportunities in Python have become a lucrative career option for people with a variety of educational backgrounds.
What are the limitations of Python?
Python does not have many restrictions. Line by line, Python code is executed. It also has a weakness in mobile computing and browsers, which causes it to be slow. Furthermore, while Python is an excellent server-side language, it is rarely used on the client side. It also has a lot of design constraints and underdeveloped database access layers.
Growing Demand for Python Programmers:
Python is one of the world's most popular programming languages. Python is used by more programmers than any other language, according to recent surveys. This increased demand for Python programmers has resulted in an increase in the number of opportunities for those with experience in this language.
