遍歷列表

嗨，我有一個月份名稱列表，但我想循環遍歷列表，從一個特定月份開始，比如說6月（第6個月），然後倒退到1月。

MonthList ={"January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"};

//total number of months
nMonths = N Items (MonthList);

//initialize list of selected months
ElevenMo = {};

For (i = 6, i <= 11, i -= 1,
 If (i >= 1, Continue () );
 nextMonth = MonthList[i];
 Insert Into (ElevenMo, nextMonth[i]),
 
);

我想我有基本知識，但是我的循環一直處於無限循環中。感謝您提出的修復建議。 是的，在某些時候循環必須回到十二月，但這將是另一場戰鬥。

這裡有2種方法來實現此目的。......我自由地添加了從要開始的月份的名稱中確定起始值的功能。兩個示例給出相同的結果

Names Default To Here( 1 );
MonthList = {"January", "February", "March", "April", "May", "June",
"July", "August", "September", "October", "November", "December"};

//total number of months
nMonths = N Items( MonthList );

targetMonth = "June";
startMonth = contains( MonthList, targetMonth );

//initialize list of selected months
ElevenMo = {};

For( i = startMonth, i >= 1, i--,
 Insert Into( ElevenMo, MonthList[i] );, 
);

Names Default To Here( 1 );
MonthList = {"January", "February", "March", "April", "May", "June",
"July", "August", "September", "October", "November", "December"};

//total number of months
nMonths = N Items( MonthList );

targetMonth = "June";
startMonth = contains( MonthList, targetMonth );
ElevenMo = MonthList[1::startMonth]

這應該工作

MonthList ={"January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"};

//total number of months
nMonths = N Items (MonthList);

//initialize list of selected months
ElevenMo = {};

For (i = 6, i > 0, i--, 
 nextMonth = MonthList[i];
 Insert Into (ElevenMo, nextMonth),
);

您好TX和ThuongLe，非常感謝您的回答。 他們也是很好的教訓。 我喜歡StartMonth和TargetMonth的優雅。
