I've also just started to learn Ruby, so thought I'd reply for the practice -
Here's one solution:


------------------------------------------------------------------------
#!/usr/bin/ruby

x = "There are 2007 beans and 15234 grains of rice in this bag."
puts x
x.gsub!(/\W/, '')
puts x

------------------------------------------------------------------------

output:

There are 2007 beans and 15234 grains of rice in this bag.
