Ending a while True loop
Introduction
We’re going to add a final touch to our Coder’s Light Switch by adding another elif condition that ends the loop without using the interrupt from Ctrl + C

1
The break block
Recall that a while True block repeats the code inside it indefinitely. In the case of this light switch, it will keep on asking for an input until we interrupt it by pressing Ctrl + C.
While this is all well and good, there’s a smoother way to break out of the loop. We can do this by utilizing the break block.
2
Using the break block
To use the break block, we can make another elif condition for ending the loop.
Let’s set the condition of this to color is “end”. Remember to put it before the else block inside our loop!
3
Adding a code after the loop
To verify that we’re breaking out of the loop, we can add a print line after the whole while True block. Run it and try out all the colors!
