dis(x=None)

Disassemble classes, methods, functions, or code.

With no argument, disassemble the last traceback.

findlabels(code)

Detect all offsets in a byte code which are jump targets.

Return the list of offsets.

findlinestarts(code)

Find the offsets in a byte code which are start of lines in the source.

Generate pairs (offset, lineno) as described in Python/compile.c.
