AttributeError: ‘bytes’ object has no attribute ‘seek’ error occurs when you try to “call the seek() method on a bytes object, but it does not exist.”
Why the error occurs
Here are two reasons for the error.
- When you use the seek() method on a raw bytes object, which doesn’t support it.
- You mistakenly thought a variable was a file-like object when it was just a bytes object.
Reproducing the error
data = b"Hello, world!"
print(data.seek(0))Output
AttributeError: 'bytes' object has no attribute 'seek'
How to fix it?
To fix the AttributeError: ‘bytes’ object has no attribute ‘seek’ error, “wrap the bytes object as a file-like object in an io.BytesIO instance.”
import io
data = b"Hello, world!"
buffer = io.BytesIO(data)
print(buffer.seek(0))
Output
0If you mistakenly thought the variable was a file-like object, review your code to understand why it contains raw bytes and adjust accordingly.
