无法解析python json.dump（）直接写入的json数据

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

这告诉我该文件确实存在，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，我得到以下错误：

Traceback (most recent call last):

您的json是什么样子的？格式正确吗？您可以通过jsonlint.com检查您的JSON中有一个

u'

，这是无效的。是否确实仅使用

json.dump

创建了该文件？该文件中没有json。您为它编写了一个Python列表，列表中有

u''，

。该文件不是用

json.dump（）

创建的，而是用

f.write（str（table））

创建的。非常感谢。在修改了ipy之后，我忘记了在ipy中重新运行一些python代码。请贴出答案。
