Simple demo of checking HTTP proxy settings and/or downloading text or HTML pages in Scala, with equivalent code in Python for comparison

ProxyTester.scala

import scala.sys.SystemProperties
import scala.io.Source.fromURL

object ProxyTester extends App {

  // Uncomment if you are behind a proxy, then edit the IP and port to match your proxy
  // val props = new SystemProperties
  //props("http.proxyHost") = "localhost"
  //props("http.proxyPort") = "8080"
  // Uncomment to see all the system properties including proxy settings
  //props foreach println

  println(fromURL("http://www.example.com").mkString)
    
  // Equivalent in python (assuming appropriate import from urllib2)
  // print urlopen('http://www.example.com').read()
  
  // Or if you want to iterate over lines:

  fromURL("http://www.example.com").getLines foreach println

  // Near-equivalent in python (assuming appropriate import from urllib2)
  // Reads in all data, rather than returning an iterator
  // for line in urlopen('http://www.example.com/').readlines(): print line,
