python - Why does my variable only return one value outside of a function? -


apologies if obvious, function creates list. printing variable of list, inside function returns list. printing global variable outside function returns first value? here 2 different versions of code:

printing inside formula works:

from itertools import chain, combinations  noise_1 = "somerandomvalue"  min_var_length = 8 max_var_length = 16  #creates powerset of input value, taking account min , max lengths def powerset(iterable):     global powerset_list     s = list(iterable)     x = list(chain.from_iterable(combinations(s, r) r in range(len(s)+1)))     x_string = list(x)     items in x_string:         if len(items) > min_var_length:                 powerset_list = items                 print(powerset_list)   powerset(noise_1)

and returns powerset of noise_1

however code returns 1 value, though printing same global variable:

from itertools import chain, combinations  noise_1 = "somerandomvalue"  min_var_length = 8 max_var_length = 16  #creates powerset of input value, taking account min , max lengths def powerset(iterable):     global powerset_list     s = list(iterable)     x = list(chain.from_iterable(combinations(s, r) r in range(len(s)+1)))     x_string = list(x)     items in x_string:         if len(items) > min_var_length:                 powerset_list = items    powerset(noise_1) print(powerset_list)

i'm guessing it's terminating function after 1 value, don't know how change behaviour. thank help! sorry r noob.

so confirm, appending list after loop creates list of of items. print command in function prints loop occur, 1 item saved in variable.

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 <...
