I assume you are talking about the "on-board", or "built-in" LEDs, and not an "add-on" LED being controlled from a GPIO pin. If that's the case, you might try incorporating the following into your code:
For the PWR (power) LED, you can turn it off like this:
echo 0 | sudo tee /sys/class/leds/led1/brightness
turn it on like this:
echo 1 | sudo tee /sys/class/leds/led1/brightness
I am talking about the add on LEDs from GPIO pins, thank you anyway

@AndreasPaxih: OK, there are lots and lots and lots of examples available that show how to do this. Why not pick one, and try it? If you hit a snag, that's what we're here for - what we're NOT here for is to search for information for you. Please take The Tour, and read how to ask a good question

It seems you are looking to execute two parts of your script at the same time. One part is controlling the flashing of the leds, the other part is executing the rest of the code. This can be done with multi threading or multi processing in python. Look at python3 threading — Thread-based parallelism and python3 multiprocessing — Process-based parallelism.

I STRONGLY suggest you don't do threading unless you're coding often or plan to put a lot of time into learning about the potential pitfalls and how to avoid them ... it's pretty much the fastest way to get a program with unreliable behaviour if you don't know what you're doing.
I would suggest you have a separate script that does the flashing; which you can then control from your other script... It's very much like threading, but because the memory isn't shared you're not going to find yourself having to debug issues you can't reproduce.
