串列 (一)

本帖最後由 鄭繼威 於 2022-8-18 23:01 編輯

• 串列,又稱為「清單」或「列表」,與其他語言的
「陣列(Array)」相同,其功能與變數相類似。
  索引值是從0 開始計數,索引值不可超出串列的範圍。
• 宣告
串列名稱(變數名稱)= [元素1, 元素2, ......]
• 範例
list1 = [1, 2, 3, 4, 5]
#元素皆為整數
list2 = ["香蕉", "蘋果", "橘子"]
#元素皆為字串
list3 = [1, "香蕉", True]
#包含不同資料型態元素

• 取得串列元素
變數名稱= 串列名稱[索引值]

假設有一串列其內容如下：
list=["忠","孝","仁","愛","信","義","和","平"]

試取出串列中的第1到第5個元素

  1. list=["忠","孝","仁","愛","信","義","和","平"]
  2. print(list[0])
  3. print(list[1:6]) #左邊是開始(有包含),右邊是結束(沒有包含)。
  4. print(list1[-1]) #取出最後一個元素值
