Well, I want to start this off, by saying that I am not leaving Python or Perl behind for Ruby, but that is the order in which I learned these 3 languages.  I learned Perl first and I used it strictly for about 3 years, then I learned Python and I have been using Python mainly since then and Perl when needed. Now since I am playing with Puppet, I figured I should go ahead and learn Ruby as well.

So far I am pretty impressed with Ruby as it reminds me of Python and Perl put together. Everything in Ruby is a Object just like it is in Python. Also you do not require a semicolon at the end of every line in Ruby like you do in Perl. You do not require a $ for a Scalar variable or a @ for an array or a % for a hash in Ruby, which you do require in Perl but not in Python. There are a lot more similarities then that, and I will post some of the commands that are similar and ones that are a bit different. Now this will not be a complete list of differences but enough so that you get the idea.

python	print "hello world" 			#This will print hello world but with a New Line at the End
ruby		puts "hello world"  			#This will print hello world but with a New Line at the End
perl		print "hello worldn";			#This will print hello world but with a New Line at the End

python	x = 8 					#x is equal to 8 which is an integer
ruby		x = 8					#x is equal to 8 which is an integer
perl		$x = 8;					#x is equal to 8 which is an integer

python	type(x)					#x is what type.... Integer, String, Class... etc
ruby		x.class					#x is of what class.... FixNum, String, Class.. etc

python	x, y, z = 1, 2, 3			#multiple assignments on one line
ruby		x, y, z = 1, 2, 3   			#multiple assignments on one line
perl		($x, $y, $z) = (1, 2, 3);   		#multiple assignments on one line

python	se = "foil"				#Assign a string to se
ruby		se = "foil"				#Assign a string to se
perl		$se = "foil"				#Assign a string to se

python	se[0:4]					#Access a slice of a string
ruby		se[0..4]				#Access a slice of a string
