pandas - Column order after multi-index unstack -


output after unstacking data. unstacked using multi-columns unstack(['marketdate','class'])

marketdate    2017/08/19 2017/08/18         2017/08/19 class             onpeak     onpeak offpeak    offpeak constraint_id                                          634              -221.65    -165.28 -116.55    -237.97 644                 0.00       2.22    0.00       0.00 1049             -702.05    -936.26 -317.45    -181.72 1281                0.00      -4.68    0.00       0.00 1607             -136.12     -84.74  -31.44     -65.91

what need see in output marketdate , below onpeak , offpeak, not marketdate onpeaks first , offpeaks later.

this important further processing.

any appreciated.

iiuc, need sort_index axis=1.

df.sort_index(axis=1)

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
