An until loop is a loop that repeats until the condition is met. The syntax for declaring an until loop is as follows:
The purpose of the 'until' loop is to keep executing a set of commands until the condition becomes false.
An until loop is a programming construct that repeats a set of commands until a specific condition is met. The condition is checked at the beginning of each iteration, and the loop continues to loop as long as the condition evaluates to false.
One advantage is that the loop will stop when it reaches the end of the list, so it doesn't need to keep checking if it is on the last element. Another advantage is that you can specify how many times you want to repeat the loop, so you don't need to keep checking how many times it has gone through.
The key difference between an until and while loop is that an until loop typically only executes when a certain condition becomes true, whereas a while loop executes indefinitely or until a certain condition becomes false.
