I prefer Ruby. But they're both fine languages in their own right when applied correctly.

Ruby is for faggots.

Ruby is fucking awful. The only thing it's notable for is being created by a Jap and adopted by brogrammers as the hipster alternative to PHP. If it was created by an old white guy, nobody would use it.

write this shorter in ruby or python



#!/usr/bin/env python

## usage: randomline.py file numlines

from sys import argv

import random

f=open(argv[1])

line=f.readlines()

f.close()

try: c = int(argv[2])

except: c = 1

for q in range(c):  print (line[random.randint(0,len(line))-1]).strip()
