timeit.py examples in docs generate error

[3c273]

Hello,
I was reading the thread on try/except overhead and decided to try Alex's
examples but they kept generating exceptions. So I went to the docs and
tried the examples there (copied and pasted) with the same results (Win2k,
Python 2.4). Any help is appreciated. The output follows:
#1
C:\Python24\Lib >timeit.py 'if hasattr(int, "__nonzero_ _"): pass'
Traceback (most recent call last):
File "C:\Python24\Li b\timeit.py", line 285, in ?
sys.exit(main() )
File "C:\Python24\Li b\timeit.py", line 249, in main
t = Timer(stmt, setup, timer)
File "C:\Python24\Li b\timeit.py", line 116, in __init__
code = compile(src, dummy_src_name, "exec")
File "<timeit-src>", line 6

Thanks again,

Window's command processor doesn't recognise single quote marks as
meaning anything special, so your command is passing 4 separate arguments
to timeit.py instead of the 1 argument that a unix shell would be passing.

Try using double quotes around everything instead:

timeit.py "if hasattr(int, '__nonzero__'): pass"

That did the trick. Thanks!
