I posted an incomplete traceback by mistake. Here is the whole traceback.

Traceback
=========
Traceback (most recent call last):
  File "seekable.py", line 5, in <module>
    print(contentFile.seekable())
  File "/usr/local/lib/python3.5/tarfile.py", line 649, in seekable
    return self.fileobj.seekable()
AttributeError: '_Stream' object has no attribute 'seekable'
