Getting Started With Python And IDE. смотреть онлайн

The interpreter is a language processor that converts a High-Level Programming Language program into machine language by converting and executing it line-by-line. If there is an error in any line, it reports it at the same time and program execution cannot resume until the error is rectified. The interpreter must always be present in the memory every time the program is executed as every time the program is run, it is first interpreted and then executed. For error debugging, the interpreter is very much useful as it reports the error at the same time. But once errors are removed, unnecessary usage of memory takes place as it has to be present in the memory always.

An integrated development environment, IDE is a software application that provides comprehensive facilities to computer programmers for software development. An IDE normally consists of at least a source code editor, build automation tools, and a debugger. Some IDEs, such as NetBeans and Eclipse, contain the necessary compiler, interpreter, or both; others, such as SharpDevelop and Lazarus, do not.

Python 3 and the Visual Studio Code IDE is used in the videos, but you can use any IDE.

The Python interactive shell shown with three arrows is a quick way to execute Python code to see how it works.
