What makes you think I'm a serious programmer? *wink*
Try this:
py> import dis # the Python disassembler
py>
py> def f(x):
... print x
... return x+1
...
py> dis.dis(f)
2 0 LOAD_FAST 0 (x)
3 PRINT_ITEM
4 PRINT_NEWLINE
3 5 LOAD_FAST 0 (x)
8 LOAD_CONST 1 (1)
11 BINARY_ADD
12 RETURN_VALUE
13 LOAD_CONST 0 (None)
16 RETURN_VALUE
Python's byte-code is not exactly as easy to understand as native Python,
but it is still understandable. And I wonder, is there a program which
will try to generate Python code from the output of the disassembler?
