Question

当我运行mu代码时，它说：

for score in scoresFile： ValueError：关闭文件的I / O操作。

我尝试过很多东西，但不会改变结果。我的代码如下所示：

SCORE_FILENAME  = "Class1.txt"
MAX_SCORES = 3

try: scoresFile = open('Class1.txt', "r+")
except IOError: scoresFile = open('Class1.txt', "w+") # File not exists
actualScoresTable = []
for line in scoresFile:
        tmp = line.strip().replace("\n","").split(",")

        for index, score in enumerate(tmp[1:]):
            tmp[1+index] = int(score)

        actualScoresTable.append({
                                "name": tmp[0],
                                "scores": tmp[1:],
                                })
        scoresFile.close()

new = True
for index, record in enumerate( actualScoresTable ):
    if record["name"] == pname:
        actualScoresTable[index]["scores"].append(correct)
        if len(record["scores"]) > MAX_SCORES:
            actualScoresTable[index]["scores"].pop(0) # OR del          actualScoresTable[index]["scores"][0]
    new = False
    break
if new:
    actualScoresTable.append({
                            "name": pname,
                            "scores": [correct],
                            })

scoresFile = open(SCORE_FILENAME, "w+") # Truncating file (write all again)
for record in actualScoresTable:

for index, score in enumerate(record["scores"]):
    record["scores"][index] = str(score)



scoresFile.write( "%s,%s\n" % (record["name"],(record["scores"])) )
scoresFile.close()

有人可以帮我解决这个问题吗。

Answer 1

将scoresFile.close()移出for循环。你在阅读完第一行后就关闭了它。

Answer 2

问题看起来是第一个for循环中的scoresFile.close()行。如果文件不止一行，那么在您尝试访问第二行时它将被关闭。我认为如果你将这条线移到循环之外，这个错误就会消失。
