Question

我有以下功能：

def readTable(self,reference_name):

    p  = self.base_path + reference_name + ".txt"

    if os.path.exists(p):
        print p
    else:
        print "oops"

    f = open(p, "r")
    data = json.loads(f.read())
    self.main_table =  data

告诉我文件确实存在，并且正在尝试读取包含json的txt文件。

json由以下调用编写：

def writeTable(table,reference_name):

    with open(reference_name + ".txt","w") as text_file:
        json.dump(table, text_file)

然而，当我转到readTable时，我收到以下错误：

Traceback (most recent call last):

    raise ValueError("No JSON object could be decoded")

文件中的数据如下所示：

无法解析由python json.dump（）直接编写的json数据
