Newbie prob: How to write a file with 3 threads?

[Flavio Preto]

Is it not possible to acomplish this with a token-based algorithm?

With 3 Threads: A, B and C

Thread A start with Token.
Thread with the token writes the byte and send the token to the next

Or python has any issues to a file object shared among a few threads?
