为什么使用eval将字符串转为字典时报错File "<string>", line 0？(语言-python)

我想使用eval将打开的txt文件转为字典，报错如下
data = eval(data_)
File "", line 0

^

SyntaxError: unexpected EOF while parsing

with open('word.txt', encoding="utf-8") as f:
        data_ = f.read()
        data = eval(data_)

怎么办啊啊

需要给对应的mode，

with open('word.txt', "r+", encoding="utf-8") as f:
    data_ = f.read()
    data = eval(data_)
    print(data)

期待您的选择。
