Shinya Kasatani developed the Selenium Integrated Development Environment in 2006. Conventionally, it is an easy-to-use interface that records the user interactions to build automated test scripts. It is a Firefox or Chrome plugin, generally used as a prototyping tool. It was mainly developed to speed up the creation of automation scripts 01. Use Built-in Libraries and Functions. Python has tons of library functions and modules. They are written by expert developers and have been tested several times. So, these functions are highly efficient and help speed up the code—no need to write the code if the function is already available in the library

Using num_update as the calculation function reduced the time for 8000 iterations on a 100x100 grid to only 2.24 seconds (a 250x speed-up). Such speed-ups are not uncommon when using NumPy to replace Python loops where the inner loop is doing simple math on basic data-types Handle Alert & Popups In Selenium Python. Whenever an Alert gets triggered and a pop-up appears on the web page, the control remains with the parent web page. So first we need to switch or transfer the control to alert pop-up before doing any operations. This control switching operation can be done by using anyone of below two code snippets Python 3.11 is slated for release in 2022.
