What’s the best way to make the first item below yield a hash instead  
of an array in one line? I’m struggling ☹

#doesnt work  
time = [“min”, “sec”].collect {|i| {i=\> Time.now.send(i).to\_i}}  
puts time.type # Array

#works  
time = [“min”, “sec”].collect {|i| {i=\> Time.now.send(i).to\_i}}.first  
puts time.type # Hash  
puts time[‘min’]

Thanks in advance

ok…nvrmind… I think I got it:  
time = Hash[\*[“min”, “sec”].collect { |i| [i, Time.now.send(i)]}.flatten]

🙂

p h

harp:~ \> ruby a.rb  
{“sec”=\>44, “min”=\>26}

in particular you don’t want to call Time.now inside the loop: you’ll  
otherwise  
sometimes get

{“sec”=\>0, “min”=\>42}

when you should have gotten

{“sec”=\>59, “min”=\>41}
