It currently shows:

    {m, n} from m to n. m defaults to 0, n to infinity
    {m, n}? from m to n, as few as possible

With the spaces before the max (n) argument. This doesn't work, which testable on the page itself.

Perhaps related -- some genius has registered http://strftime.org and lists out python strftime formatting directives. Very handy as a quick reference.

What's wrong with "man date" ? ;) Except of course if you are using Windows in which case manpages are a no-no.

This is really nice, but I've always enjoyed RegexPal [1]. It's got a nice clean simple UI, displays results immediately and allows me to prototype regular expressions very quickly. Use it almost every time I wrote a regex. [1] http://regexpal.com/

The problem is, regex flavors differ, and RegexPal uses JavaScript - whose regex flavor is really limited compared to most others (including Python). You should always try to find a tool that uses the regex flavor you are targeting.
