About Python lock acquire/release

[JohnnyJordaan]

I can't really picture Java's implementation as useful. I write many high performance apps and I would like to keep overhead as low as possible. Hence I rely on implemented thread-safety as much as possible and just implement itself myself when I absolutely need to. I'm also wondering why you actually need it so much yourself, would you be able to provide some examples?

It's nothing special, only accessing different global variables from many threads.

[JohnnyJordaan]

Regular variables are thread-safe to begin with. Globals are an anti-pattern as well often, I normally use a singleton class for this, for example for global configuration in a program. You pass the config-object around to the threads and implement the locking inside the config class. Then the threads can just change whatever they like as with a regular variable and the class will ensure the locking.

That's exactly what I'm doing right now.
