Small usefull program - Vi-Sion - 11-23-2016

So i was really bored had that idea to code something useful in small lines of code .
I ended up coding a small program to randomly choose a movies from some movies i choose why well it happens a lot to me that i have some movies to watch and can't choose which one to watch first.

Spoiler:Code:
import java.util.Scanner;
import java.util.Random;
public class Movies {
    public static String[] chooseYourMovies(){
        Scanner in=new Scanner(System.in);
        in.useDelimiter("\\n");
        System.out.println("how many movies you want to enter :");
        String []movies=new String[in.nextInt()];
        for(int i=0;i<movies.length;i++){
            System.out.println(i);
            movies[i]=in.next();}
        return movies;}
public static void randomMovie(String[]movies){
Random rand=new Random();
System.out.println(movies[rand.nextInt(movies.length)]);}
    public static void main(String[] args) {
        randomMovie(chooseYourMovies());
    }}

your turn what can you code something useful in a max of 20 lines ?

20 lines is a lot of freedom if you know how to use it effectively. Run the program with a question mark as the first argument to see the syntax.

Code:
from urllib.parse import unquote
from requests import get
from sys import argv

if argv[1]=='?':
	print("usage: python projectfinder.py [hot|new] [hour|day|week|month|year|all] [0-100]")
	exit()

def get_settings():
	if len(argv)==1: return ['hot','week','5']
	return argv[1:].extend(['week','5'][:-(len(argv)-3)])

query=get(
	"https://www.reddit.com/r/ProgrammingPrompts/{}.json?t={}&limit={}".format(*get_settings()),
	headers={'user-agent': 'project-picker/0.1.0'}
).json()

for c in query['data']['children']:
	print("\"%s\"\nlink: %s author: %s\n"%(unquote(c['data']['title']),'https://redd.it/'+c['data']['id'],c['data']['author']))

@Inori if i'm not mistaken your using a library here, that's not what i was looking to see.

I'm using a library for an http request; I could use urllib, which is part of the Python Standard Library, but it's shitty and bulky.

Get public ip in 2 lines of Python:

Code:
import urllib2
urllib2.urlopen("http://icanhazip.com").read().decode("utf-8")
