Question

我有这个数组：

[

"org-dummyemail-123-AccountName",
"org-dummyemail-123-Email",
"org-dummyemail-123-PAT",
"org-dummyemail-123-PATName",
"org-dummyemail-123-PATValidTo",
"org-dummyemail1-joemarmoto-AccountName",
"org-dummyemail1-joemarmoto-Email",
"org-dummyemail1-joemarmoto-PAT",
"org-dummyemail1-joemarmoto-PATName",
"org-dummyemail1-joemarmoto-PATValidTo"
]

并希望对其进行整理，并制作两个独立的数组，像这样

[
"org-dummyemail-123-AccountName",
"org-dummyemail-123-Email",
"org-dummyemail-123-PAT",
"org-dummyemail-123-PATName",
"org-dummyemail-123-PATValidTo"
]


[
"org-dummyemail1-joemarmoto-AccountName",
"org-dummyemail1-joemarmoto-Email",
"org-dummyemail1-joemarmoto-PAT",
"org-dummyemail1-joemarmoto-PATName",
"org-dummyemail1-joemarmoto-PATValidTo"
]

希望能为您提供帮助！谢谢：）

Answer 1

简单的数组过滤：

def highscore():


   file_highscore = open('scores_test2.txt' , 'r')
   scores_and_names = []
   scores = []
   scores_2 = []
   names = []
   for line in file_highscore.readlines():
      score_info = line.split()

      scores_and_names.append(line)
      scores_2.append(scores_and_names[line][])

      scores.append(score_info[1])
      names.append(score_info[0])


   scores.sort(key = int)
   scores.sort(reverse = True)



   print('The First 5 Highscores are:')
   for item in scores[:5]:

      print(item)

另一种不同的方法是使用@BindingAdapter("imageUrl") public static void setImageUrl(ImageView view) { //Now get image view instance to provide width and height. } cmdlet对计算所得的属性进行分组。您没有指定要排序的确切部分-虚拟电子邮件或其后的名称-因此我在虚拟电子邮件之后使用了该部分。

结果为您提供了一个数组的集合，这些数组的名称为[计算出的属性]，一组为[与该计算出的属性匹配的项目]。您可以单独处理它们，也可以使用它们来制作新阵列。

Group-Object

输出...

$AllNames = @(
    'org-dummyemail-123-AccountName',
    'org-dummyemail-123-Email',
    'org-dummyemail-123-PAT',
    'org-dummyemail-123-PATName',
    'org-dummyemail-123-PATValidTo'
    'org-dummyemail1-joemarmoto-AccountName',
    'org-dummyemail1-joemarmoto-Email',
    'org-dummyemail1-joemarmoto-PAT',
    'org-dummyemail1-joemarmoto-PATName',
    'org-dummyemail1-joemarmoto-PATValidTo'
    )

# 3rd item index = 2
$PartToGroupOn = 2

$GroupedAllNames = $AllNames |
    Group-Object -Property {$_.Split('-')[$PartToGroupOn]}

$GroupedAllNames[1].Group

Answer 3

将输入作为Json对象处理（来自here字符串）脚本

使用Select-Object和
从前三个- /破折号分隔的部分中构建密钥计算的属性。
按此键分组
从组值中重建Json对象。

$Json = @"
[
"org-dummyemail-123-AccountName",
"org-dummyemail-123-Email",
"org-dummyemail-123-PAT",
"org-dummyemail-123-PATName",
"org-dummyemail-123-PATValidTo",
"org-dummyemail1-joemarmoto-AccountName",
"org-dummyemail1-joemarmoto-Email",
"org-dummyemail1-joemarmoto-PAT",
"org-dummyemail1-joemarmoto-PATName",
"org-dummyemail1-joemarmoto-PATValidTo"
]
"@ | ConvertFrom-JSon

$Json | Select-Object @{n='key';E={($_ -split '-')[0..2] -join '-'}},
                      @{n='value';e={$_}} |
    Group-Object key | ForEach-Object{
        $_.Group.Value | ConvertTo-Json
    }

具有以下输出：

[
    "org-dummyemail-123-AccountName",
    "org-dummyemail-123-Email",
    "org-dummyemail-123-PAT",
    "org-dummyemail-123-PATName",
    "org-dummyemail-123-PATValidTo"
]
[
    "org-dummyemail1-joemarmoto-AccountName",
    "org-dummyemail1-joemarmoto-Email",
    "org-dummyemail1-joemarmoto-PAT",
    "org-dummyemail1-joemarmoto-PATName",
    "org-dummyemail1-joemarmoto-PATValidTo"
]

Answer 4

使用$ PSItem变量

$arr="org-dummyemail-123-AccountName",
"org-dummyemail-123-Email",
"org-dummyemail-123-PAT",
"org-dummyemail-123-PATName",
"org-dummyemail-123-PATValidTo",
"org-dummyemail1-joemarmoto-AccountName",
"org-dummyemail1-joemarmoto-Email",
"org-dummyemail1-joemarmoto-PAT",
"org-dummyemail1-joemarmoto-PATName",
"org-dummyemail1-joemarmoto-PATValidTo"

$arr2 = $arr | Where-Object {$PSItem -match 'joemarmoto'}
$arr3 = $arr | Where-Object {$PSItem -match '123'}

在这里看看：https://blogs.msdn.microsoft.com/mvpawardprogram/2013/04/15/working-with-the-new-psitem-automatic-variable-in-windows-powershell-3-0/

从该站点：获取有关about_Automatic_Variables -ShowWindow的帮助

在“查找”框中键入“ psitem”以突出显示包含该单词的所有文本：

我们可以看到，$ PSItem与$ _相同。引入$ PSItem变量的目的是使包含“管道中当前对象”的代码更易于阅读和理解。

答案与Gert Jan Kraaijeveld几乎完全相同，但是很清楚$ PSItem的作用以及该信息的来源。

以下是使用正则表达式确定输入字符串的哪一部分分组依据的版本：

clear-host

'REGEX 1; org-dummyemail-123 vs org-dummyemail1-joemarmoto'

$groupedByAllButLast = @(
"org-dummyemail-123-AccountName",
"org-dummyemail-123-Email",
"org-dummyemail-123-PAT",
"org-dummyemail-123-PATName",
"org-dummyemail-123-PATValidTo",
"org-dummyemail1-joemarmoto-AccountName",
"org-dummyemail1-joemarmoto-Email",
"org-dummyemail1-joemarmoto-PAT",
"org-dummyemail1-joemarmoto-PATName",
"org-dummyemail1-joemarmoto-PATValidTo"
) | Group-Object -Property @{E={$_ -replace '([^-]+-[^-]+-[^-]+)-.*', '$1'}} 

for ([int]$i = 0; $i -lt $groupedByAllButLast.Count; $i++)
{
    Write-Verbose $groupedByAllButLast[$i].Name -Verbose
    $groupedByAllButLast[$i].Group
}

'REGEX 2; 123 vs joemarmoto'
$groupedByTheNameOrEmailBit = @(
"org-dummyemail-123-AccountName",
"org-dummyemail-123-Email",
"org-dummyemail-123-PAT",
"org-dummyemail-123-PATName",
"org-dummyemail-123-PATValidTo",
"org-dummyemail1-joemarmoto-AccountName",
"org-dummyemail1-joemarmoto-Email",
"org-dummyemail1-joemarmoto-PAT",
"org-dummyemail1-joemarmoto-PATName",
"org-dummyemail1-joemarmoto-PATValidTo"
) | Group-Object -Property @{E={$_ -replace '[^-]+-[^-]+-([^-]+)-.*', '$1'}} #all we've changed is the location of the opening bracket in this line 

for ([int]$i = 0; $i -lt $groupedByTheNameOrEmailBit.Count; $i++)
{
    Write-Verbose $groupedByTheNameOrEmailBit[$i].Name -Verbose
    $groupedByTheNameOrEmailBit[$i].Group
}

NB：这基本上与Lee's相同；仅使用regex捕获字符串中与我们的键相关的所有部分，而不是使用split并取一个符号段...有关此有用功能的更多信息，请参见MS Docs
