python - TypeError: 'int' object does not support item assignment -



python - TypeError: 'int' object does not support item assignment -

why error?

a[k] = q % b typeerror: 'int' object not back upwards item assignment

code:

def algorithmone(n,b,a): assert(b > 1) q = n k = 0 while q != 0: a[k] = q % b q = q / b ++k homecoming k print (algorithmone(5,233,676)) print (algorithmone(11,233,676)) print (algorithmone(3,1001,94)) print (algorithmone(111,1201,121))

you're passing integer function a. seek assign as: a[k] = ... doesn't work since a scalar...

it's same thing if had tried:

50[42] = 7

that statement doesn't create much sense , python yell @ same way (presumably).

also, ++k isn't doing think -- it's parsed (+(+(k))) -- i.e. bytcode unary_positive twice. want k += 1

finally, careful statements like:

q = q / b

the parenthesis utilize print imply want utilize on python3.x @ point. but, x/y behaves differently on python3.x on python2.x. looking @ algorithm, i'm guessing want integer division (since check q != 0 hard satisfy floats). if that's case, should consider using:

q = q // b

which performs integer partition on both python2.x , python3.x.

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...
