Tried all method, dont know how do ,.....I make a loop and thread, setup for example 3 thread, when take a line from a .csv want to be unique in every thread and on loop to not repeat
i run five threads at once.
I want to run another function when these 5 operations are finished or when the error occurs, and then I need to run these 5 threads again.
for example, when one thread is successful, it will wait for the others to finish.
