 What is the difference between client-side validation and server-side validation?





Client-Side Validation: - In the client-side validation method, all the input validations and error recovery process is carried out on the client-side i.e. on the user’s browser. It can be done using JavaScript, AJAX, VB Scripts, Python, and Perl, etc.

Here the validation process works without sending data to the server for processing. Example:-

Suppose you want to validate whether a user-entered email is in the right format.




Server-Side Validation: - In server-side validation, all the input validations and error recovery process is carried out on the server-side. It can be done using programming languages like C#.NET, Java, etc.

Note: - Client-side validation is faster than server-side because the validation takes place on the client-side (on a browser) and the networking time from client to server is saved.

Server-side validation is more secure than the client-side as the user cannot see the code even he does a view-source.

 Python IDEs and Code Editor | PyCharm Python IDEs and Code Editor: A code editor is a tool that is used to write and edit code. They are usually lightweight and can be great for learning. However, once your program gets larger, you need to test and debug your code, that's where IDEs come in. An IDE (Integrated Development Environment) understands your code much better than a text editor. It usually provides features such as build automation, code inline, testing, and debugging. This can significantly speed up your work. Following are the editor we can use for python coding: 1.    PyCharm (We preferred) 2.     Eclipse 3.    Atom 4.    Thonny 5.     Visual Studio 6.    Spyder 1.    PyCharm (We preferred):   Pycharm provides smart code inspections, code completion, error highlighting, along with automated code refactorings and rich navigation capabilities.
