dis — Python Bytecode Disassembler — PyMOTW 3
The dis module includes functions for working with Python bytecode by “disassembling” it into a more human-readable form. Reviewing the bytecodes being executed by the interpreter is a good way to hand-tune tight loops and perform other kinds of optimizations. It is also useful for finding race conditions in multi-threaded applications, since it can be used to estimate the point in the code where thread control may switch.
