Python_报错：TypeError: file must have 'read' and 'readline' attributes

Python 报错：TypeError: file must have ‘read‘ and ‘readline‘ attributes

    在运行序列化（pickle）相关功能时报错：TypeError: file must have ‘read‘ and ‘readline‘ attributes

 

上代码：

>>> fp = open("a.txt","r+")
>>> import pickle
>>> pickle.load("fp")#提示报错

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: file must have ‘read‘ and ‘readline‘ attributes

原因分析：在load()方法里的参数写错了，多了一个“”，去掉即可

 

解决：

改成如下方法即可

>>> fp = open("a.txt","rb+")
>>> import pickle
>>> pickle.load(fp)#序列化打印结果
[‘apple‘, ‘mango‘, ‘carrot‘]
