CSV notes at https://ruby-doc.org/stdlib-2.6.3/libdoc/csv/rdoc/CSV.html

str.strip
 
# use a regular expression ( this evaluates to 
str = "white chocolate"
str.gsub("white", "dark")

"a1".gsub(/(\w)(\d)/, '\2\1')
 
# puts and print
print "use a return at the end\n"
puts "automatically adds the newline"
