either the tutorial is wrong, or you didn't look closely enough. :-)
The string starts with ' ', not '\t'.
The string starts with ' ', which isn't in the character set.
The '\s' description is on link:

I can see that the space is missing. It should say:
\s Matches whitespace. Equivalent to [ \t\n\r\f].
Could you give me an example to use the equivalent pattern?
(I'm using Python 3.4, which is why the match object looks different.)
>>> import re
>>> re.match(r'\s*\d\d*$', ' 111')
<_sre.SRE_Match object; span=(0, 6), match=' 111'>
>>> re.match(r'[ \t\n\r\f]*\d\d*$', ' 111')
<_sre.SRE_Match object; span=(0, 6), match=' 111'>
