TypeError：強制轉換爲Unicode：需要字符串或緩衝區，找到類型，函數

Question

我正在嘗試編寫一個程序，它使用函數來打開文件，然後使用文件中的行來玩一個紙牌遊戲，但我一直在這個錯誤。

Traceback (most recent call last): File "/home/ecunning/Documents/Treasure Hunt Game Lab", line 115, in drawCard() File "/home/ecunning/Documents/Treasure Hunt Game Lab", line 102, in drawCard deck = readDeck(file) File "/home/ecunning/Documents/Treasure Hunt Game Lab", line 26, in readDeck infile = open(fileName , 'r') TypeError: coercing to Unicode: need string or buffer, type found

這裏是我的代碼：

def getfileName(): 
    fileName = raw_input("What is the name of the file?: ") 
    return fileName 

    while (fileName != fileDescription): 
     print("Invalid file name. Select an appropriate file: ") 
     fileName = raw_input("What is the name of the file?: ") 
     return fileName 

def readDeck(fileName): 
    infile = open(fileName , 'r') 
    deck = [] 

    for card in infile: 
     print card 
    return deck 

def getCardType(deck): 
    cardType = input("What is the location of the card would you like to extract from the deck: ") 
    card = deck[cardType] 
    return card 
    print card 

    while (cardType > len(deck)): 
     print "This location is not in the deck. Re-enter a location that is within the list" 
     cardType = input("What is the location of the card would you like to extract from the deck: ") 
     card = deck[cardType] 
     return card 
     print card 

    newDeck = deck.remove(str(card)) 

    cardGroup = card[:1] 
    return cardGroup 
    print cardGroup 

    if str(cardGroup) == ruby: 
     print "This card is a ruby" 
    elif str(cardGroup) == emerald: 
     print "This card is an emerald" 
    elif str(cardGroup) == coal: 
     print "This card is coal" 
    else: 
     print "This card is a diamond" 


def getCardValue(card): 
    cardValue = card[2:] 
    cardAmount = int(cardValue) 
    return cardAmount 

def displayList(card): 
    drawnCards = [] 
    drawnCards.append(card) 
    drawnCards.sort() 
    print ("List of drawn cards: ") ,drawnCards.sort() 

def getPosition(): 
    cardType = input("What is the location of the card would you like to extract from the deck: ") 
    card = newDeck[cardType] 
    return card 
    print card 

    while (cardType > len(deck)): 
     print "This location is not in the deck. Re-enter a location that is within the list" 
     cardType = input("What is the location of the card would you like to extract from the deck: ") 
     card = deck[cardType] 
     return card 
     print card 

def drawCard(): 
    cardtotal = 0 
    while (cardtotal < winValue): 
     getfileName() 
     deck = readDeck(file) 
     cardType = getCardType(deck) 
     if (str(cardGroup) != coal): 
      cardtotal = cardtotal + cardAmount 
      print cardtotal 
      getCardValue(card) 
      displayList(card) 
      cardType = getPosition() 
     else: 
       print "You drew a coal card. The game is over" 
    print "You have drawn 21 points! You win!" 

drawCard() 

任何幫助將是巨大的！謝謝。

您會看到此錯誤消息，因爲您傳遞的是該對象上的function對象而不是string對象。我想像你正在嘗試做的是這樣調用這個方法：

deck = readDeck(getfileName()) 

你似乎也有與程序變量的作用域和控制流的許多問題，所以我建議你read up onyour problems，然後去通過你的程序並修復你所看到的所有問題
