function - python - sieve of Eratosthenes when number is prime print "1" when not print "0" -

-

i must create function f(n) value 1 when number prime or value 0 when isn't prime. code working prints in revers order. example: f(6)= 0 0 1 1 0 1 0

def prime(n):     if n<2: return false     in range(2,n):         if n%i == 0:             return false     return true  def f(n):     print('0', end=' ')     a=1     while a<=n:         n=n-1         print('1' if prime(n) else '0', end=' ')  f(6)

reverse loop like:

def f(n):   print('0')   in range(1, n+1):     print('1' if prime(a) else '0')

ps have seen examples of how actually implement sieve of eratosthenes in python on stack overflow, worth searching better solution.

i wish write custom appender on basis of outputstreamappender . wrote following class package tests; import java.io.ioexception; import java.io.outputstream; import ch.qos.logback.core.outputstreamappender; public class myappender<e> extends outputstreamappender<e> { public myappender() { system.out.println("myappender created"); setoutputstream(new outputstream() { @override public void write(int b) throws ioexception { throw new unsupportedoperationexception(); } }); } } then wrote following runner: package tests; import org.slf4j.loggerfactory; import ch.qos.logback.classic.logger; public class runner { private static final logger log = (logger) loggerfactory.getlogger(runner.class); public static void main(string[] args) { //log.addappender(new myappender<iloggingevent>()); log.info("hello world"); } } finall...

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
