Python
Python is a flexible language easier to learn than most other languages, but still powerful enough to be useful for solving real-life problems, used from MIT for learning programming to NASA and Google. Main project homepage is http://python.org/

Code:

# Hello World in Python
print "Hello World"

Perl
Perl is often used as a glue language, tying together systems and interfaces that were not specifically designed to interoperate, and for "data munging", ie. converting or processing large amounts of data for tasks like creating reports. In fact, these strengths are intimately linked. The combination makes perl a popular all-purpose tool for system administrators, particularly as short programs can be entered and run on a single command line.

Code:

#!/usr/bin/perl
# Hello world in perl
use warnings;

print "Hello World!\n";
