python - How to display a 2D list in this form? -


how can convert 2d list this?

lista=[[1, 2, 3],[3, 4, 5],[8, 5, 9]]   listb=[[1 2 3]        [3 4 5]        [8 5 9]]

as pointed out, have same representation of 1 list in python, list list conversion doesn't make sense. however, if want list string conversion - ways output list nice string, have option of pprint, or pretty-printing. module standard library seems pretty close you're looking for:

import pprint  l = [[1, 2, 3],[3, 4, 5],[8, 5, 9]]  pprint.pprint(l, width=12)

gives output

[[1, 2, 3],  [3, 4, 5],  [8, 5, 9]]

now i've had artificially reduce maximum width bit lists short pprint, default, not consider them worth shortening.

also, if want string representation in program, can use pprint.pformat in pretty same way, except returns string:

import pprint  l = [[1, 2, 3],[3, 4, 5],[8, 5, 9]]  s = pprint.pformat(l, width=12)

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 <...
