What the...? Hash does not have a key it really should have!

Hi all

irb(main):001:0> conversion_classes = {
irb(main):002:1* ‘Music labels’ => ‘MusicLabel’,
irb(main):003:1* ‘Music artists’ => ‘MusicArtist’,
irb(main):004:1* ‘Online Shops’ => ‘OnlineShop’,
irb(main):005:1* ‘Psy Communities’ => ‘PsyCommunity’,
irb(main):006:1* }
=> {“Psy Communities”=>“PsyCommunity”, “Music labels”=>“MusicLabel”,
“Online Shops”=>“OnlineShop”, “Music artists”=>“MusicArtist”}
irb(main):007:0> conversion_classes.has_key? “Music Labels”
=> false

What the heck is wrong here? I’m feeling quite blind at the moment, lol!

Thanks
Josh

I’d say because in the hash you set the key ‘Music labels’, then you ask
if it
has the key ‘Music Labels’.

You’re capitalizing “Labels”.

I lined them up (for proportional fonts). See the difference yet?

You’re creating the key with a lowercase ‘l’ and trying to read it out
with a capital ‘L’…

Is that the blunder?
