tuple pairs, finding minimum, python -



tuple pairs, finding minimum, python -

i have info comes tuple pairs within python, e.g.

data = [ (1, 7.57), (2, 2.1), (3, 1.2), (4, 2.1), (5, 0.01), (6, 0.5), (7, 0.2), (8, 0.6)]

how may find min of dataset comparing of sec number only? i.e. data[0][1] = 7.57, data[1][1] = 2.1.. min( info ) = (5, 0.01)

i see min( info ) returns (1, 7.57), take right minimum within pair, though not of dataset.

in [2]: min(data, key = lambda t: t[1]) out[2]: (5, 0.01)

or:

in [3]: import operator in [4]: min(data, key=operator.itemgetter(1)) out[4]: (5, 0.01)

python tuples min

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
