python - Return a string of country codes from an argument that is a string of prices -


so here's question:

write function return string of country codes argument string of prices (containing dollar amounts following country codes). function take argument string of prices following: "us$40, au$89, jp$200". in example, function return string "us, au, jp".

hint: may want break original string list, manipulate individual elements, make string again.

example:

> testequal(get_country_codes("nz$300, kr$1200, dk$5") > "nz, kr, dk"

as of now, i'm clueless how separate $ , numbers. i'm lost.

def test(string):     return ", ".join([item.split("$")[0] item in string.split(", ")])  string = "nz$300, kr$1200, dk$5" print test(string)

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 <...
