How to stop a while loop after N amount of time?
Sometimes when you loop like this, you may not want to consume the CPU for the entire allotted time. For example, say you are checking the value of something that changes every second. If you don’t introduce some kind of delay, you would use every available CPU cycle allotted to your process.
Is the statement Test-1 useless in a loop?
The statement test = test – 1 is useless regardless of what it does because the variable is reset at the beginning of the next iteration of the loop. Even if you changed it to be test = 5, the loop would still be infinite because the value is reset each time.
Is it possible to make a while Loop infinite?
Even if you changed it to be test = 5, the loop would still be infinite because the value is reset each time. If you move the initialization statement outside the loop, then it will at least have a chance to exit.
What happens if I move the initialization statement outside of the loop?
If you move the initialization statement outside the loop, then it will at least have a chance to exit. What you may have intended was something like this: The order of the statements in the loop depends on the logic of your program. It will work in either order, though, which is the main point.
Do you need to use while true in while loop?
You do not need to use the while True: loop in this case. There is a much simpler way to use the time condition directly: Petr Krampl’s answer is the best in my opinion, but more needs to be said about the nature of loops and how to optimize the use of the system.
How long does a Python loop run for?
I have a while loop, and I want it to keep running through for 15 minutes. it is currently: (this runs through, and then restarts. I need it to continue doing this except after 15 minutes it exits the loop) Thanks! This will run for 15 min x 60 s = 900 seconds. Function time.time returns the current time in seconds since 1st Jan 1970.
