Python Error: TypeError: file must have ‘read’ and ‘readline’ attributes

Error when running serialization (pickle) related functions: TypeError: file must have ‘read’ and ‘readline’ attributes

Code above.

>>> fp = open("a.txt","r+")
>>> import pickle
>>> pickle.load("fp")#error
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: file must have 'read' and 'readline' attributes

Cause analysis: the parameter in the load () method is wrongly written. If there is one more “” and it can be removed

Solution:

Change to the following method

>>> fp = open("a.txt","rb+")
>>> import pickle
>>> pickle.load(fp)#Serialized Print Results
['apple', 'mango', 'carrot']
