在python2.7中使用itertools,如何表示代码的哪些部分(在链接中突出显示)应该重复?另外,计数迭代器还是组合迭代器更适合这种情况?我在ArcGIS中列出ID的编号(numid)和引用字段(使用arcpy)来创建一个新类型的ID。目标是缩短代码,现在列出每个numid和行[x]=“…-(01)”。这是我正在尝试编写和迭代器的代码:
if numIDs == "1":
row[3] = "(" + row[0] + ") - (" + row[1] + ") - (" + row[2] + ") - (01)"
cursor.updateRow(row)
elif numIDs == "2":
row[3] = "(" + row[0] + ") - (" + row[1] + ") - (" + row[2] + ") - (01)"
row[4] = "(" + row[0] + ") - (" + row[1] + ") - (" + row[2] + ") - (02)"
cursor.updateRow(row)
elif numIDs == "3":
row[3] = "(" + row[0] + ") - (" + row[1] + ") - (" + row[2] + ") - (01)"

我不知道你想做什么,但那代码让我想躲在灌木丛下。你知道吗
这与您的代码完全相同:
