why the "\s{6}+" is not a regular pattern?
Why are you too lazy to do any research before posting a question?
Errr... what?
I'm only somewhat familiar with the extra stuff that languages provide
in their regexs beyond true regular expressions and simple extensions,
but I was surprised to see the question because I too would have
expected that to work. (And match any sequence of whitespace characters
whose length is a multiple of six.) I reskimmed the documentation of the
re module and didn't see anything that would prohibit it. I looked at
several of the results of a Google search for the multiple repeat error,
and didn't really find any explanation beyond "because you can't do it"
or "here's a regex that works." (Well, OK, I did see a mention of +
being a possessive quantifier which Python doesn't support. But that
still doesn't explain why my expectation isn't what happened.)
In what way is that an unreasonable question?
