The dis module can be effectively used to disassemble Python methods, functions and classes into low-level interpreter instructions.
I know that dis information can be used for:
1. Find race condition in programs that use threads
2. Find possible optimizations
From your experience, do you know any other scenarios where Disassembly Python feature could be useful?
I see the
dismodule as being, essentially, a learning tool. Understanding what opcodes a certain snippet of Python code generates is a start to getting more “depth” to your grasp of Python — rooting the “abstract” understanding of its semantics into a sample of (a bit more) concrete implementation. Sometimes the exact reason a certain Python snippet behaves the way it does may be hard to grasp “top-down” with pure reasoning from the “rules” of Python semantics: in such cases, reinforcing the study with some “bottom-up” verification (based on a possible implementation, of course — other implementations would also be possible;-) can really help the study’s effectiveness.
