How can i use internal iteration within function in python? -


i need code run : 

pp = ["first", "second", "third"] sum(d d in pp)

i error:

typeerror: unsupported operand type(s) +: 'int' , 'str'

i guess there lazy evaluation. please me this?

thank you!

sum() buildin function default start 0. takes numbers , return total. not allowed string. so, above error. rather, can join list using ''.join() function.

like : 

pp = ["first", "second", "third"] sum = ''.join(pp) print(sum)

output : 

firstsecondthird

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 <...
