The short answer is, maybe. Python will be CPU bound but not I/O
bound. This means you can have multiple threads concurrently
performing I/O. On the other hand, if you have two threads which are
CPU bound, only one will run at a time.
Having said that, there are plenty of ready work arounds.

In situations like this, you need to guard the resource with a mutex.
In Python, things like insertions are atomic but iterations are not.
Thusly, if you wrap it with a mutex, things can be made safe. I saw,
can be, because you then have to ensure you always use the mutex to
satify your
