Once you get used to writing things in the Mathematica language, all sorts of fun things become possible. This morning I printed a set of small two-sided Mexican flags that we'll wrap around toothpicks, glue together and stick into Krispy Kreme doughnuts tonight:
TableForm[
Partition[
Table[
Framed[
CountryData["Mexico", "Flag"]
],
{24}
],
2
],
TableSpacing -> {Automatic, 2}
]
and I just solved a little regular expression problem posed by my boss:
> What's the regex for matching a three digit version number? > > Valid examples (where 'x' is an integer > 0) > x > x. > x.x > x.x. > x.x.x
Howzabout -
In[19]:= strings = {"6", "6.", "6.0", "6.0.", "6.0.1"} Out[19]= {"6", "6.", "6.0", "6.0.", "6.0.1"} In[30]:= StringMatchQ[#, RegularExpression["[0-9](\.([0-9](\.([0-9])?)?)?)?"]] & /@ strings Out[30]= {True, True, True, True, True}
