Try Ruby is a interactive shell that quickly and whimsically teaches the Ruby programming language. Originally _why's idea, it has been recreated from the ground up by Rubyists who have a passion for Ruby and for teaching their fellow (wo)man how to program.

poem.delete doesn't work #148

Open avjgit opened 12 years ago

avjgit commented 12 years ago

gives out error "ArgumentError: wrong number of arguments (at least 1) "

davidmiani commented 12 years ago

poem is a String, and the delete method on String requires one argument. Eg poem.delete "aeiou" will return a string containing the contents of poem but with all the vowels deleted.

So this is correct behaviour.

okay, but the instructions in the tutorial just say: try poem.delete they do not say: try poem.delete "aeiou"

tedkspradley commented 12 years ago

hmmm... I agree that the behavior should be to delete all of the vowels according to the string methods documentation, however, my experience is this:

poem.delete "aeiou"
ArgumentError: wrong number of arguments (at least 1)

tedkspradley commented 12 years ago

it may be related to something else, b/c the next command in the tutorial is to create an empty hash called 'books', but I get the same ArgumentError

books ={}
ArgumentError: wrong number of arguments (at least 1)

It appears that the string (or whatever data structure) called poem no longer exists for me in the tutorial.

print poem
ArgumentError: wrong number of arguments (at least 1)
