是否可以在 Iron python 中使用字符串对动态数组进行排序

本文关键字：动态 字符串 数组 排序 Iron python 是否 | 更新日期: 2023-09-27 18:35:40

我正在 spotfire 中编写一个铁 python 代码，通过传递现有的数据表过滤器，根据需要从数据表中提取数据。问题是用户希望按照他们指定的特定排序顺序对值进行排序。问题是：如果我们有整个数据表，我们可以通过浏览列属性 ->排序顺序 ->自定义排序顺序并排列它们来对行中的值进行排序。但是现在我们没有完整的值，所以我们如何在铁蟒脚本或 spotfire 中处理它。

是否可以在 Iron python 中使用字符串对动态数组进行排序

我做了类似的工作，将数字值排序为字符串。

我的建议是创建一个计算列，根据您希望的排序方式在实际字符串之前添加空格。 在 Spotfire 可视化中，它会修剪字符串，以便用户不会看到它未对齐，并且所有内容都相应地排序。

如果这是一项简单的任务，则可以直接在计算列的表达式中完成。

我的例子： 

If([AR Days]<>"(PA)",
If(Integer([AR Days])>360,">360",
If(Integer([AR Days])>359," " & [AR Days],
If(Integer([AR Days])>349,"  " & [AR Days],
If(Integer([AR Days])>339,"   " & [AR Days],
If(Integer([AR Days])>329,"    " & [AR Days],
If(Integer([AR Days])>319,"     " & [AR Days],
If(Integer([AR Days])>309,"      " & [AR Days],
If(Integer([AR Days])>299,"       " & [AR Days],
If(Integer([AR Days])>289,"        " & [AR Days],
If(Integer([AR Days])>279,"         " & [AR Days],
If(Integer([AR Days])>269,"          " & [AR Days],
If(Integer([AR Days])>259,"           " & [AR Days],
If(Integer([AR Days])>249,"            " & [AR Days],
If(Integer([AR Days])>239,"             " & [AR Days],
If(Integer([AR Days])>229,"              " & [AR Days],
If(Integer([AR Days])>219,"               " & [AR Days],
If(Integer([AR Days])>209,"                " & [AR Days],
If(Integer([AR Days])>199,"                 " & [AR Days],
If(Integer([AR Days])>189,"                  " & [AR Days],
If(Integer([AR Days])>179,"                   " & [AR Days],
If(Integer([AR Days])>169,"                    " & [AR Days],
If(Integer([AR Days])>159,"                     " & [AR Days],
If(Integer([AR Days])>149,"                      " & [AR Days],
If(Integer([AR Days])>139,"                       " & [AR Days],
If(Integer([AR Days])>129,"                        " & [AR Days],
If(Integer([AR Days])>119,"                         " & [AR Days],
If(Integer([AR Days])>109,"                          " & [AR Days],
If(Integer([AR Days])>99,"                           " & [AR Days],
If(Integer([AR Days])>89,"                            " & [AR Days],
If(Integer([AR Days])>79,"                             " & [AR Days],
If(Integer([AR Days])>69,"                              " & [AR Days],
If(Integer([AR Days])>59,"                               " & [AR Days],
If(Integer([AR Days])>49,"                                " & [AR Days],
If(Integer([AR Days])>39,"                                 " & [AR Days],
If(Integer([AR Days])>29,"                                  " & [AR Days],
If(Integer([AR Days])>19,"                                   " & [AR Days],
If(Integer([AR Days])>9,"                                    " & [AR Days],
                          "                                     " & [AR Days]))))))))))))))))))))))))))))))))))))),
                          "                                      (PA)")

对于更复杂的示例，我允许用户为类似的存储桶选择自定义大小分组，最终存储桶的硬上限为 360+。 此值是文本输入框中的整数（名为 udBucketSize 的属性），更改时的脚本如下所示：

bck = Document.Properties["udBucketSize"]
if bck < 10:
    x = 'If([ACCOUNT LOCATION (2)]="1","                                     (PA)",'
else:
    x = 'If([ACCOUNT LOCATION (2)]="1","    (PA)",'
y = ')'
oldbck = 0
if bck == 1:
    x = "[AR Days Workaround]"
else:
    while oldbck + bck < 360 and bck > 0:
        if oldbck == 0:
            x += 'If(DateDiff("day",[FINAL BILL DATE],[SNAPSHOTDATE])<=' + str(oldbck + bck) + ',"'
        else:
            x += 'If(DateDiff("day",[FINAL BILL DATE],[SNAPSHOTDATE])<=' + str(oldbck + bck - 1) + ',"'
        if bck < 10:
            z = (360 - oldbck)/10 + 1
            n = 1
            while n <= z:
                x += ' '
                n += 1
        else:
            if oldbck < 100:
                x+= '    '
            elif oldbck < 200:
                x+= '   '
            elif oldbck < 300:
                x+= '  '
            else:
                x+= ' '
        if oldbck == 0:
            x+= str(oldbck)  + '-' + str(oldbck+bck) +'",'
            oldbck += 1
        else:
            x+= str(oldbck)  + '-' + str(oldbck+bck - 1) +'",'
        y+= ')'
        oldbck += bck
    x += 'If(DateDiff("day",[FINAL BILL DATE],[SNAPSHOTDATE])<=360," ' + str(oldbck) + '-360", ">360")' + y
    print x
Document.Properties["udBucketString"] = x

属性 udBucketString 当时是我的计算列的表达式，现在按我想要的方式排序。

类似的方法可用于对字母或特殊字符进行排序。
