Why I am getting this "NameError: name 'trainingData' is not defined"

Question

我尝试按如下方式导入 training.txt 数据。

def readTrainingData(training):
    
    trainingData=[]
    
    with open(training.txt) as f:
        
        for line in f:
            a1, a2 = line.strip().split()
            trainingData.append((a1, a2))
    return trainingData

之后我尝试使用训练数据来测量一些分数，如下所示：

for pair in trainingData:
  linkScores[pair[0]+''+pair[1]]= computeProximityScore(pair[0],pair[1],'Jaccard',neighbors)

但是报错

----> 1 trainingData

NameError: name 'trainingData' is not defined

有人能帮帮我吗？

谢谢

当你将变量 training 传递给函数时，我不明白你试图做什么。但是当你打开一个文件时，你需要这样做：

```with open("file_name.txt") as f:```

此外，您不能在函数外访问变量 trainingData。

我更新了你的代码（我希望它是你想要的）：

Main（或您运行函数的任何其他地方）：

trainingData = readTrainingData("training.txt")
# The rest of your code.

你的函数：

def readTrainingData(training):
    trainingData = []

    with open(training) as f:
        for line in f:
            a1, a2 = line.strip().split()
            trainingData.append((a1, a2))
    return trainingData
