I'm trying to get a array from a string passed as parameters to match a dictionary after.
My code:
def substrings(*args, dictionary)
words = args.to_s.split(" ")
puts words[0]
puts words[1]
puts words[2]
end
substrings("below as above", dictionary)
The result is
["below
as
above"]
Why the first and last elements has this [" and "]??
Hope I was clear.
* in *args means that you collect arbitrary amount of arguments in array args, so "below as above" transforms into ["below as above"] array, and .to_s converts it into string '["below as above]', that's why you receive this strange result.
If you want only one (first) string argument, you may change code as below:
def substrings(str, dictionary)
words = str.split
puts words[0]
puts words[1]
puts words[2]
end
substrings("below as above", dictionary)
# output:
# below
# as
# above
Or, if you really want to pass any amount of strings:
def substrings(*args, dictionary)
words = args.map(&:split).flatten
words.each { |word| puts word }
end
substrings("below as above", "foo is not a bar", dictionary)
# output:
# below
# as
# above
# foo
# is
# not
# a
# bar
