TypeError: Coercing zu Unicode: brauche String oder Puffer, Typ gefunden, Funktionen

Question

Ich versuche ein Programm zu schreiben, das Funktionen verwendet, um eine Datei zu öffnen und dann die Zeilen in der Datei zu verwenden, um ein Kartenspiel zu spielen, aber ich bekomme weiter dieser Fehler.

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

Hier ist mein Code:

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() 

Jede Hilfe wäre toll !! Vielen Dank.

Answer 1

Sie erhalten diesen Fehler, weil Sie ein function Objekt anstelle eines string Objekts in dieser Zeile übergeben. Ich kann mir vorstellen, was Sie versuchen, diese Methode zu tun nennen ist wie folgt:

deck = readDeck(getfileName()) 

Sie scheinen auch zahlreiche Probleme mit variablem Umfang und Kontrollfluss in Ihrem Programm zu haben, so empfehle ich Ihnen read up onyour problems und dann gehen durch Ihr Programm und beheben Sie alle Probleme, die Sie sehen
