Question

我正在尝试从juliabox读取终端输入。问题是，它接受输入的唯一方法是我把答案放在引号之间。在我的情况下，我必须使用“是”或“否”来获得正确的行为。

response = readline()
 if response == "yes"

有什么方法可以将输入转换为字符串以消除对引号的需要？

Answer 1

最明确的做法是＆＃34;是＆＃34;在你的例子中。＆＃34; ＆＃34;字符创建字符串类型。

> typeof("yes")
ASCIIString

或者，您可以存储字符串并与之进行比较：

yes_str = "yes"
no_str = "no"
if response == yes_str
  # yes stuff
end

或一个干净的想法，检查多个回复：

yes_strs = ["yes", "y", "yeah", "sure", "ok", "ya", "positive", "affirmative", "pos"]
no_strs = ["no", "n", "nah", "nope", "na", "negative", "negatory", "neg"]

# Convert to lower case for matching
response = lowercase(readline()) 

if response in yes_strs
  # yes stuff
elseif response in no_strs
  # no stuff
else
  println("I don't understand, give me a yes or no.")
  # other stuff
end
