Often, we represent the values we want to process as a range (an actual list), or xrange (which … Read more

When is while(true) true, and when is it false? It’s always true, it’s never false. Some people use while(true) loops and then use break to exit them when a certain condition is true, but it’s generally quite sloppy practice and not recommended. Without the use of break, return, System.exit(), or some other such mechanism, it will keep looping forever.

Exit while loop in Python

The while loop will match the condition only when the control returns back to it, i.e when the for loops are executed completely. So, that’s why your program doesn’t exits immediately even though the condition was met. But, in case the condition was not met for any values of a,b,c then your code will end up in an infinite loop.
