Python Introduction, What is Python? 1/43 33, , Python is a popular, interpreted, high-level, general purpose programming language. It was created, by Guido van Rossum, and released in 1991., , It is used for:, , web development (server-side),, software development,, mathematics,, , system scripting, , What can Python do?, , Python can be used on a server to create web applications., , Python can be used alongside software to create workflows., , Python can connect to database systems. It can also read and modify files., , Python can be used to handle big data and perform complex mathematics., , Python can be used for rapid prototyping, or for production-ready software development., , Good to know, , « The most recent major version of Python is Python 3, which we shall be using in this tutorial., However, Python 2, although not being updated with anything other than security updates, is, still quite popular., , « In this tutorial Python will be written in a text editor. It is possible to write Python in an, Integrated Development Environment, such as Thonny, Pycharm, Netbeans or Eclipse which, are particularly useful when managing larger collections of Python files., , Python Syntax compared to other programming languages, , + Python was designed for readability, and has some similarities to the English language with, influence from mathematics., , « Python uses new lines to complete a command, as opposed to other programming languages, which often use semicolons or parentheses., , « Python relies on indentation, using whitespace, to define scope; such as the scope of loops,, functions and classes. Other programming languages often use curly-brackets for this, purpose., , What is Python IDLE?, After installing python just goto start manu and find will find “IDLE(Python3.7)”.IDLE Stands, , for Integreted Development Environment. This is a by default Development Environment for, Python.There are many more development environment like Pycharm, Eclipse, Eric stc., , 1.Python Syntax, , As we learned in the previous page, Python syntax can be executed by writing directly in the, Command Line:, , >>> print("Hello, World!"), Hello, World!, , Or by creating a python file on the server, using the .py file extension, and running it in the, Command Line:, , C:\Users\Your Name>python myfile.py, , Python Indentation, , Indentation refers to the spaces at the beginning of a code line., , Where in other programming languages the indentation in code is for readability only, the, indentation in Python is very important., , Python uses indentation to indicate a block of code., , Example, , if 5 > 2:, print("Five is greater than two!"), , Python will give you an error if you skip the indentation:, , Example
