Why to use loop condition

Question

tell me about use loop condition

Answer 1

For example, if you wanna print the sentence "hello world" on the screen 100 times you can use the for loop instead of typing print."hello world " 100 times in your code.

Answer 2

Loops allow you to run a segment of code repeatedly - for a number of times or until a condition is met.
The condition is "what you want to happen"!

So if myValue is True, then my while-loop would run forever; if it was False, it wouldn't run at all.

(bool) myValue = true;
while myValue {
//etcetera blahblah
break
}

You can change the loop condition with a simple:
myValue = False; //or True, your choice
from inside or outside the loop. Simple stuff!
You *will* want to use loops with Loop Conditions to run repeatitive code, unless you want to type your stuff one-by-one, line-by-line. (A painful experience, trust me...)
