Methods that return a value Code Challenge/Ruby Loops
In that code challenge I get asked to
Fill out the parse_answer method to return the answer passed in. If the kind is number, convert it to an integer using the to_i method before returning it.
This is the given code:
def parse_answer(question, kind="string") end
As this is very similar to the previous video I thought I input: def parse_answer(question, kind="string") answer = gets.chomp answer = answer.to_i if kind == "number" return answer end
But I don't pass the challenge with this. Can anybody explain to me what this challenge is expecting?
The question isn't written that well, actually, because it should say 'if kind is "number"', not 'if kind is number'.
'answer' is an argument and so is 'kind' (set to "number" by default).
def parse_answer(answer, kind="string") if kind == "number" answer.to_i else answer end end
If you don't fully understand what's going on here, post it up and me or someone else will help you out.
I agree as well, this was the first Treehouse exercise I was stumped on. Judging from what they just taught us in the previous lesson, I would expect the code to look more along the lines of:
def parse_answer(answer, kind="string") puts "Enter something, anything: " answer = gets.chomp answer = gets.chomp.to_i if kind == "number" return answer end
