In this Python tutorial, we will discuss how to fix Python 3 pickle typeerror a bytes-like object is required not ‘str’ error.
Recently, I was trying to read a file using the pickle module in python. I got an error: TypeError: a bytes-like object is required, not ‘str’. Below is the code I used for reading a file.
import pickle
file = open('student.p', 'r')
student = pickle.load(file)
file.close()
print(student)
You can see the error screenshot, how the pickle typeerror a bytes-like object is required not ‘str’ error appearing.
typeerror a bytes-like object is required not ‘str’ python 3
The solution is very simple, here we have to use ‘rb’ instead of ‘r’ in the below line of code:
file = open('student.p', 'rb')
The full code looks like below:
import pickle
file = open('student.p', 'rb')
student = pickle.load(file)
file.close()
print(student)
Now, when you execute the code, the error typeerror a bytes-like object is required not ‘str’ python 3 will not appear.
