列表與元組的區別：元組（tuple）可以含有任意型別資料的序列，但它是不可變的，而列表（list）能做元組能做的任何事情，格式上元組是由一對圓括號包裹，而列表由一對方括號包裹。而且不止這些，列表是可變的，元素可以新增到列表中，也可以把元素從中刪除，也能對它進行排序。因此，元組的用法，都可以用到列表上。
以下程式是對列表的一些操作：包括建立列表，對列表遍歷，使用len()函式，對列表進行索引，切片，連線，通過列表的可變性，對它進行通過索引賦值，通過切片賦值，還有對列表進行元素的刪除，列表切片的刪除。

inventory = ["sword","armor","sheild","healing potion"
 
]
print("The item you have:",end = " ")
#print(inventory,end = " ")
for item in inventory:
           print(item,end = " ")
input("\nPress the enter key to continue.")
print("\nYou have",len(inventory),"items in your possession.")
input("\nPress the enter key to continue.")
if "healing potion" in inventory:
           print
 
("\nYou will live to fight another day.")
index = int(input("\nEnter the index number for an item in your inventory:"))
print("At index",index,"is",inventory[index-1],".")
beginnum = int(input("\nEnter the index number to begin a slice:"))
endnum = int(input("Enter the index number to end the slice:"
 
))
print("inventory[",beginnum,":",endnum,"] is",inventory[beginnum-1:endnum-1])
input("\nPress the enter key to continue.")
chest = ["gold","gems"]
print("You find a chest which contains:")
print(chest)
print("\nYou add the contents of chest to your inventory.")
print("Your inventory now is:")
inventory += chest
print(inventory)
input("\nPress the enter key to continue.")
print("You use your gold and gems to buy an orb of future telling.")
inventory[4:6] = ["orb of future telling"]
print("Now your inventory is:",inventory)
input("\nPress the enter key to continue.")
print("In a battle your shield is destroyed.")
del inventory[2]
print("Your inventory is now:",inventory)
input("\nPress the enter key to continue.")
print("You trad your sword for a crossbow.",end = " ")
print("Unfortunately your new crossbow and armor are stolen by detestable thieves ")
inventory[0] = ["crossbow"]
del inventory[:2]
print("Now your inventory is:",inventory)
input("\nPress the enter key to continue.")

列表方法：
append(value) : 將value新增到列表末尾
sort() :對元素進行排序，小值在前。可以為reverse引數設定一個布林值。如果設定的是TRUE，則列表將以“大值在
前”的方式排列順序。
reverse()：反轉列表的順序。
count(value)：返回value出現的次數。
index(value)：返回value第一次出現的位置編號。
insert(i，value)：將value插入到位置i。
pop([i]):返回位置i的值，並將其從列表中刪除。也可以不指定位置編號i，這樣的話，被刪除並返回的就是列表的最後一個元素。
remove(value):刪除列表中第一次出現的value。

使用列表方法的例子：

Scores = [500,200,300,1000,5000]
print("""
         High Scores
         0----Exit
         1----Show Scores
         2----Add a Score
         3----Remove a Score
         4----Sort Scores
      """)
yourwill = input("\nDo you want to choose from these choices?Yes or No :")
if yourwill.lower() == 'yes':
           choice = int(input("\nEnter your choice:"))
           while choice in range(0,5):
                      if choice == 0:
                                 print("\nYou will exit!")
                                 input("\nPress the enter key to exit!")
                                 break
                      elif choice == 1:
                                 print("\nHigh Scores\n",Scores)
                                 choice = int(input("Choose again?:"))
                      elif choice == 2:
                                 newscore = int(input("\nWhat score did you get?:"))
                                 Scores.append(newscore)
                                 print("Now the new score list is:",Scores)
                                 choice = int(input("Choose again?:"))
                      elif choice == 3:
                                 print("\nNow the score list is:",Scores)
                                 removescore = int(input("Which score do you want to remove from the score list?:"))
                                 if removescore in Scores:
                                            Scores.remove(removescore)
                                            print("Now the new score list is：",Scores)#print裡面不能直接將Scores換成Scores.remove(removescore)
                                            choice = int(input("Choose again?:"))
                                 else:
                                            print("The score you give is illegal.")
                                            choice = int(input("Choose again?:"))

                      else :
                                 Scores.sort(reverse = True)
                                 print("\nThe score list that has been sorted is:",Scores)
                                 choice = int(input("Choose again?:"))
           print("The choice is illegal!")
