これが私のサンプルプログラムです:
what = {:banana=>:fruit, :pear=>:fruit, :sandal=>:fruit, :panda=>:fruit, :apple=>:fruit}
what.map do |w|
p "is this right?"
awesome_print w
fix = gets
fix.chop!
if (fix == "N")
p "Tell me what it should be"
correction = gets
w[1] = correction.chop!.to_sym
end
p w
end
私はそれを実行し、これを取得します(私の入力が含まれています):
"is this right?"
[
[0] :banana,
[1] :fruit
]
Y
[:banana, :fruit]
"is this right?"
[
[0] :pear,
[1] :fruit
]
Y
[:pear, :fruit]
"is this right?"
[
[0] :sandal,
[1] :fruit
]
N
"Tell me what it should be"
footwear
[:sandal, :footwear]
"is this right?"
[
[0] :panda,
[1] :fruit
]
N
"Tell me what it should be"
animal
[:panda, :animal]
"is this right?"
[
[0] :apple,
[1] :fruit
]
Y
[:apple, :fruit]
=> [[:banana, :fruit], [:pear, :fruit], [:sandal, :footwear], [:panda, :animal], [:apple, :fruit]]
>> what
=> {:banana=>:fruit, :pear=>:fruit, :sandal=>:fruit, :panda=>:fruit, :apple=>:fruit}
私の質問は、ハッシュを変更するにはどうすればよいですか? irb は、プログラムを実行すると、列挙された各要素が処理されることを通知しますが、結果は hash に保存されませんwhat
