A better explanation for “while”???

I KEEP LOOKING AT THE WHILE LOOP ARTICLE BUT I STILL DONT UNDERSTAND IT. IS THERE SOMEONE WHO CAN DESCRIBE IT BETTER??? Ex. I KEEP SEEING THE “while True” AND CONFUSED ON LIKE, WHEN THE LOOP STOPS.

Dominic I am assuming you meant "any_statement==true" and not "any_statement=true".

Grab a paper and a pen and write down a while loop, go over each line with your pen acting as a debugger and think about what is happening... Lets use pseudo code for simplicity and lets initialize an integer (i) with the value 0. At each loop I will add 1 to i. When i reaches 5 I will break the while loop: Int i = 0; While ( any_statement==true ) { // true by default causes an // infinite loop i += 1; If ( i == 5 ) { // this will break out the // while loop any_statement=false; } }

I understand you are talking about the 'while' loop in Python. The loop is enabled while something is true. Hence, it is called 'while'. Here is an example. num = 6 while num > 0: num -= 1 if num == 2: break print(num) We create a variable num and set its value to 6. Then we create a 'while' loop, that loops while our variable 'num' is more than 0. Every time it loops, it subtracts 1 from our variable num, and checks if it is 3. If it isn't, it outputs the num variable. If it is, the loop ends. The output should give you: 5 4 3 The 'break' statement stops the loop.

You can use the 'break' statement in code whenever you want to stop the loop.

okay so while True is an infinate loop that can get broken by “break”?

Ignore "break" lets just understand while loops for now. I explained it as best I could. https://code.sololearn.com/cP8XY4hMhob2/?ref=app
