修改

class Tof
  def Tof.etiology
    puts "NS displacement of the infundibular septum"
  end
   def Tof.pathophys
    puts "VSD, Overriding of the Aorta, RVH, pulmonary stenosis"
  end
end

puts "What would you like to know?"

如何让用户输入Tof.etiology，以便puts语句显示

Answer 1

（有问题的新代码的编辑答案）

您应该能够通过简单的继承来实现它。

class Foo
   def m1
     puts "method 1"
   end
   # ...
   def m7
     puts "method 7"
   end
end

class Bar < Foo
end

class Baz < Foo
end

bar = Bar.new
bar.m1 # method 1

baz = Baz.new
baz.m1 # method 1

你也可以制作模块Foo并使用mixin。

可以使用初始答案处理第二部分：

puts "what would you like to know?"
answer = gets.chomp

case answer
when "Tof.etiology"
  Tof.etiology
when "Tof.othermethod"
  Tof.othermethod
end

在模块中显示用户调用的方法＆amp;类
