DEFINITION OF PYTHON:
Python is a popular, simple, High-Level programming and Object-Oriented Language. Python language was created by Guido Van Rossum. Sir Guido Van Rossum is also known as the Father of Python Programming. Python language is released in 1991.
Python is also an interpreted scripting language. It is simple and easy to learn and provides lots of high-level data structures. Python is an easy-to-learn yet powerful and versatile scripting language
Our Python tutorial includes all topics of Python Programming such as installation, control statements, Strings, Lists, Tuples, Dictionaries, Modules, Exceptions, Date and Time, File I/O, Programs, etc. There are also given Python interview questions to help you better understand Python Programming.
Python is a dynamic, interpreted (bytecode-compiled) language. There are no type declarations of variables, parameters, functions, or methods in Python.
WHAT IS PYTHON?
Python is an easy-to-learn, powerful programming language. It has efficient high-level data structures and a simple but effective approach to object-oriented programming. Python’s elegant syntax and dynamic typing, together with its interpreted nature, make it an ideal language for scripting and rapid application development in many areas on most platforms.
Python is an easy-to-learn yet powerful and versatile scripting language, which makes it attractive for Application Development.
With its interpreted nature, Python's syntax and dynamic typing make it an ideal language for scripting and rapid application development.
Python supports multiple programming patterns, including object-oriented, imperative, and functional or procedural programming styles.
Python is not intended to work in a particular area, such as web programming. It is a multipurpose programming language because it can be used with web, enterprise, 3D CAD, etc.
We don't need to use data types to declare variable because it is dynamically typed, so we can write a=10 to assign an integer value in an integer variable.
Python makes development and debugging fast because no compilation step is included in Python development, and the edit-test-debug cycle is very fast.
Python has many web-based assets, open-source projects, and a vibrant community. Learning the language, working together on projects, and contributing to the Python ecosystem are all made very easy for developers.
Because of its straightforward language framework, Python is easier to understand and write code in. This makes it a fantastic programming language for novices. Additionally, it assists seasoned programmers in writing clearer, error-free code.
Python is an easy-to-learn, powerful programming language. it has efficient high-level data structures and a simple but effective approach to object-oriented programming.
Python is an open-source, cost-free programming language. It is utilized in several sectors and disciplines as a result.
In Python, code readability and maintainability are important. As a result, even if the code was developed by someone else, it is easy to understand and adapt by some other developer.
Python has many third-party libraries that can be used to make its functionality easier. These libraries cover many domains, for example, web development, scientific computing, data analysis, and more.
BASIC SYNTAX OF PYTHON:
We are not to use curly braces and semicolons in Python Programming language it is like the English language. But Python programming language is using indentation to define a block of code. Indentation is nothing but it adds whitespace before the statement when it is needed.

| Basic Syntax |
In the above example, the statements that are the same level to the right belong to the function. Generally, we can use four whitespaces to define indentation.
Instead of Semicolon as used in other languages, Python ends its statements with a Newline character.
Python is a case-sensitive language, which means that uppercase and lowercase letters are treated differently. For example, 'name' and 'Name' are two different variables in Python.
In Python, comments can be added using the '#' symbol. Any text written after the '#' symbol is considered a comment and is ignored by the interpreter. This trick is useful for adding notes to the code or temporarily disabling a code block. It also helps in understanding the code better by some other developers.
'If', 'otherwise', 'for', 'while' 'try', 'except', and 'finally' are a few reserved keywords in Python that cannot be used as variable names. These terms are used in the language for particular reasons and have fixed meanings. If you use these keywords, your code may include errors, or the interpreter may reject them as potential new Variables.
Feature Of Python Language:
1. SIMPLE LANGUAGE:
Python is an Easily understandable language. In This Programming Language, We Can Not Use Curly Braces and Semicolons. Indentation is Defined as a Block of code.
2. OBJECT-ORIENTED LANGUAGE:
Python is an Object-Oriented Language. In this Programming Language, We Use the Classes and Objects. Python supports inheritance, Polymorphism, Encapsulation, etc. Python supports the Object-Oriented Language. the Object-Oriented Programming Language Helps the Programmers to use code Usability.
3. FREELY AND OPEN SOURCE: -
Python is a Free Available Software Available for Everyone on its official website www.python.org.
it is the largest community in the world that is dedicatedly working towards making new Python modules and functions. open source means that "anyone can download the source code of Python programming".
4. INTERPRETED LANGUAGE:
Python Language is an interpreted language, Interpreted language means that the Python code Executes line-by-line. he executes one line at a time. the advantage of being interpreted language, it makes debugging easy and portable.
5. CROSS PLATFORM-LANGUAGE:
Cross-platform means we can run any program on various types of Windows like (google, Chrome, etc.) So we can say that Python is a portable language.
