Allocating a shared array to python threads?

Question

Python

Please help, I just can't figure out how to distribute the array between threads, so that each thread would work with its own values ​​and not take the values ​​of other threads.
For example:
a = [1,2,3,4,.....10000]
And there are 10 threads how to make the threads work in place with this array and not take already taken values?
threading library
