  How do you manage concurrency problems in Python code? I know they have answers for objects like 𝚕𝚒𝚜𝚝 and 𝚍𝚒𝚌𝚝, but What is the equivalent of the Java 𝚜𝚢𝚗𝚌𝚑𝚛𝚘𝚗𝚒𝚣𝚎𝚍 keyword? Are you supposed to use primitives like 𝙻𝚘𝚌𝚔 from https://docs.python.org/3/library/threading.html https://docs.python.org/3/library/threading.html It seems to me one could make a @𝚜𝚢𝚗𝚌𝚑𝚛𝚘𝚗𝚒𝚣𝚎𝚍 annotation that would do nothing in a GIL Python but use a lock in a GIL-free Python.

    >What is the equivalent of the Java 𝚜𝚢𝚗𝚌𝚑𝚛𝚘𝚗𝚒𝚣𝚎𝚍 keyword? The closest equivalent would be using a lock, semaphore or barrier object with a context manager .i.e. the with keyword. Making the locking and unlocking of data automatically managed for you. I generally try to stick to a deque in Python if I am doing anything concurrent.
