poem.delete doesn't work

[avjgit]

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

[davidmiani]

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"

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]

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)
