Turn on a LED after pressing a button for certain time, even after releasing it

Hello I am new to Arduino and I've reading tutorials, but I'd like to know how to press a button and turn on a LED for ten seconds, even after releasing the button.

Thanks for your help

Have you got a program that reads an input ? Have you got a program that changes the state of an output ?

Have you looked at and tried the examples in the IDE ?

Have you looked at and tried the examples in the IDE ?

Specifically, the blink without delay example and the state change detection example. Between them, all the clues you need.
