Question

我正在访问元组的内容。每次运行代码时，我都会得到错误消息索引超出范围。我试图使用for循环来完成元组。我已经尝试了一切并失败了。

代码如下：

# Check friend(s) selection
myTuple = chat_FriList.get(0,END) 
tup = chat_FriList.curselection()
selected_friends = Listbox()        # to hold selected friends for group chat
selected_friends.delete(0, END)

for item in tup:
    user = myTuple[int(tup[item])]
    selected_friends.insert(END, user)

if (len(tup) !=0):
    print "Selected name:" + myTuple[int(tup[0])]
    count=0
    while count < len(friend_list):
        msg = friend_list[count]
        print selected_friends
        if dpkg(msg)[3] in selected_friends:           #dpkg(msg)[3] == myTuple[int(tup[0])]:
            connect_client(myID, myPort, dpkg(msg)[1], int(dpkg(msg)[2]), 'C', EntryText)
    count +=1

完整代码在此链接上。基本上我试图创建一个群聊。大多数工作，但我努力与所选用户进行群聊。任何帮助将不胜感激。看完整代码： client.py

完全回答这个问题需要更多信息，但REPL中的以下示例应该会有所帮助。代表您进行更多调试可能是最好的策略。

a = ("a", "b", "c")
for item in a
    print a[item]

a = (0, 1, 2)
for item in a
    print a[item]

a = (10, 11, 21)
for item in a
    print a[item]
