Ewww!!!! What a Ruby-esque interface, that makes me sad :-( And what if you have your own profile global name? And *wrong* too. `__builtins__` is a private CPython implementation detail. The way to monkey-patch the built-ins in Python 2 is to inject the object into `__builtin__` (no s), or `builtins` in Python 3. Seeing as line_profiler is written in C, perhaps the author (Robert Kern) doesn't care about supporting Jython or IronPython, but there may be Python implementations (PyPy perhaps?) which can run C code but don't have __builtins__. In any case, it sounds like it isn't working. Try creating this simple file: # demo.py print(profile) # Does profile actually get injected into the builtins? then running it: kernprof -l demo.py If that still gives a NameError, you have a bug in kernprof. Or possibly you have broken it -- perhaps you are accidentally shadowing one of its modules with a module of your own? -- Steven -- https://mail.python.org/mailman/listinfo/python-list
