I meant timeit.py has classes. OK, I called timeit.py with this template: template = """ def inner(_it, _timer): %(setup)s _t0 = _timer() for _i in _it: %("x=0" "while x<100": " x*x")s _t1 = _timer() return _t1 - _t0 """ And got this error: E:\Python25\Scripts-NotMine>timeit.py Traceback (most recent call last): File "E:\Python25\Scripts-NotMine\timeit.py", li sys.exit(main()) File "E:\Python25\Scripts-NotMine\timeit.py", li t = Timer(stmt, setup, timer) File "E:\Python25\Scripts-NotMine\timeit.py", li src = template % {'stmt': stmt, 'setup': setup KeyError: '"x=0" "while x<100": " x*x"' So what's the error? I've probably misunderstood how to do the substitution.. Dick _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
