While Loops

I'm getting different results from these two and I thought they meant the same thing. For example, if I say while variable: does that mean while the variable is true?

So What's the difference:

''' while True: '''

and

''' while variable: '''

if I say while variable: does that mean while the variable is true? Yes. Using while variable: means while the value of the variable is "truthy", that is, evaluates to a non-zero value. For objects like lists and strings, it means "non-empty". The list [] and the empty string "" will be considered false. All other lists and strings are considered "True".

The loop while True will not end, unless a break statement is reached.

Post back if you need more help. Good luck!!
