将用户输入与数组中的元素进行比较而忽略空格

I want to compare a user input player with the elements in an array players:

我想将用户输入播放器与阵列播放器中的元素进行比较:

players = ["KYRIE IRVING", "KEVIN DURANT", "KAWHI LEONARD"]

If player is in players disregarding spaces in player, then I want to move forward; otherwise, I want it to display an error message. For example, if player is "KYRIE IRVING", "Kyrie Irving", "kyrie irving", or "kyrieirving", I want to move forward.

如果玩家在玩家中无视玩家的空间,那么我想继续前进;否则,我希望它显示错误信息。例如,如果玩家是“KYRIE IRVING”,“Kyrie Irving”,“kyrie irving”或“kyrieirving”,我想继续前进。

The following code doesn't work with "kyrieirving".

以下代码不适用于“kyrieirving”。

def valid_player(player, fan, players, vote_history)
  until players.include?(player) || **players.gsub(/\s+/, "").include?(player)**
    puts "\n   Oops! That's not a valid player. Please try again."  
    print "\n   Fan #{fan}: "  
    player = gets.chomp.upcase 
  end 
 vote_history << player
end

I could create another array that has all the elements of players without the spaces, then compare with that. I also could create a block in which the gsub method applies to each element of the array. I'm assuming there's a cleaner solution than either of these two options though.

我可以创建另一个包含没有空格的玩家所有元素的数组,然后与之比较。我还可以创建一个块,其中gsub方法适用于数组的每个元素。我假设有一个比这两个选项中的任何一个更清晰的解决方案。

A few points

几点

puts in ruby includes a newline so you don't need to begin your strings with newline if you call puts.

put in ruby包含换行符,因此如果你调用puts,你不需要用换行符开始你的字符串。
I find its easier to store everything in lower case, not upper case. Much easier to read.

我发现它更容易以小写字母存储所有内容,而不是大写字母。更容易阅读。
I would use recursion to check for a valid response, not a loop.

我会使用递归来检查有效的响应,而不是循环。

something like this:

像这样的东西:

def valid_player(fan, players, vote_history)
    player = gets.strip
    player_no_spc = player.gsub(" ","").downcase
    players_no_spc = players.map{ |s| s.gsub(" ","")}

    if players_no_spc.include?(player_no_spc)
       return vote_history << player
    else
       puts "Oops! That's not a valid player. Please try again."
       puts "Fan #{fan}: "
       valid_player(fan, players, vote_history)
    end
end

#2

players = %w|KYRIEIRVING KEVINDURANT KAWHILEONARD|
player_to_check = "Kyrie IRVING"
if p = players.detect? { |p| p == player_to_check.delete(' ').upcase }
  puts "Found: #{p}"
else
  puts "Oops!"
end

#3

The following will match kyrieirving:

以下将匹配kyrieirving:

re = /KYRIE IRVING/mix

The follwoing will match KYRIE IRVING, Kyrie Irving, kyrie irving :

接下来将与KYRIE IRVING,Kyrie Irving,kyrie irving相匹配:

re = /KYRIE IRVING/mi

x stands for ignore whitespace... you may prepare two regex one with x flag and another without and apply both while iterating through your array. Otherwise you will have to apply things (which I think would have been better) that you have mentioned in your post as FORBIDDEN :)

x代表忽略空格...你可以用x标志准备两个正则表达式而另一个没有并在迭代数组时应用两者。否则你将不得不申请你在帖子中提到的FORBIDDEN :)(我认为会更好)

re = /KYRIE IRVING/mi
str = 'KYRIE IRVING, Kyrie Irving, kyrie irving, or kyrieirving,'

# Print the match result
str.scan(re) do |match|
    puts match.to_s
end
