將字典附加到主列表

Question

由於某些原因，它不讓我將字符串項添加到字典中的某個鍵。

這裏是我的代碼：

例如 splitUserList(line)

：

>>> splitUserList("1|24|M|technician|85711 ") 
['1', 24, 'M', 'technician', '85711'] 

代碼：

def createUserList(): 
    userList = [] 
    totalUserList = [] 
    f = open("u.user.txt") 
    for line in f: 
     userDict = {} 
     singleUserList = splitUserList(line) 
     userDict["age"] = singleUserList[1] 
     userDict["gender"] = singleUserList[2] 
     userDict["occupation"] = singleUserList[3] 
     singleUserList["zip"] = singleUserList[4] 
     userList.append(userDict) 
    return userList 

爲什麼不工作？

Traceback (most recent call last): 
    File "/Applications/WingIDE.app/Contents/MacOS/src/debug/tserver/_sandbox.py", line 1, in <module> 
    # Used internally for debug sandbox under external interpreter 
    File "/Applications/WingIDE.app/Contents/MacOS/src/debug/tserver/_sandbox.py", line 20, in createUserList  
TypeError: list indices must be integers, not str 

Answer 1

我猜你的意思

userDict["zip"] = singleUserList[4] 

，而不是

singleUserList["zip"] = singleUserList[4] # <-- singleUserList is a list, 
              #  and you cannot index it via a string
