E.g. we have to print "Hello World" on the screen. If we use Java we have to write code like below: Class HelloWorld { Public main( [] args) { System.out, printIn( ); } } static void String "Hello World!" If we use Python then we have to write code like: Print( ) "Hello, World!" Now you can see why Python is easy to learn and execute. What is Python Development Environment? The Python development environment consists of a text editor and python runtime implementation. Due to text editor, we can write code for our application. The runtime implementation such as CPython or PyPy provides the method of executing your codes. A text editor is simple like notepad running on windows or more complicated Integrated Development Environment (IDE) with syntax checking and code highlighting. It is a software application that combines all of the features and a tool needed by software developers. It is graphical. It uses windows and controls like the button to display information. It accepts input from the users. A tool includes A text editor: it is a window for input, arrangement and commenting of programming language code. A project editor: It shows all of the files that make up the software project. A toolbar: It is a set of buttons that represents the function that environment can perform. An output viewer: It displays any message that the environment generates during the operation. There are lots of IDE for Python development such as IDLE, PyCharm, VScode, PyDev, Eclipse etc. but common IDE for Python development is PyCharm which can run on any major operating system. Why do we need IDE? It is not compulsory to use IDE but as a developer, but it makes life easier. The code insight is one of the most helpful tools that IDE provides. The program changes the text color to represent different classes, functions and variables. Due to IDE, debugging of the program becomes easy. Testing is a crucial part to make sure that the program doesn't have any error. Whenever writing a new program, different files have a reference in a specific path location. So it is very important for running the program that these files are in the correct location. Using IDE it becomes easy. Advantages of IDE are below: Increased efficiency: Faster coding with less effort Collaboration: A group of programmers can easily work together within an IDE.
