Python 3.2 won't import cookielib

Question

I have looked everywhere for this and just cannot find the answer. I have checked my python version and it is version 3.2 . When I try to import cookielib I receive:

ImportError: No module named cookielib

I have seen that in Python 3.0 it was renamed to http.cookiejar and that it would auto import cookielib.

I thought that maybe there was some wild error in my python configuration so I thought I should try and import http.cookiejar like this import http.cookiejar. That did not work all and I get and error:

EOFError: EOF read where not expected.

This is not the error I had expected becuase import http.cookies imports just fine.

Does anybody have a solution to this problem? What am I overlooking?

Full Error:

Traceback (most recent call last):
  File "C:\Users\Spencer\Downloads\selenium-2.20.0.tar\selenium-2.20.0\selenium-2.20.0\test", line 1, in <module>
    import urllib.request, urllib.parse, http.cookiejar
EOFError: EOF read where not expected

The automatic renaming business only applies if you use 2to3. Therefore, you have to import http.cookiejar.

The error EOFError: EOF read where not expected is only ever thrown by Python marshalling. Most likely, this is caused by a race condition fixed in Python 3.3, where multiple processes tried to write concurrently to the pyc file. Deleting all .pyc files may be a workaround.

For those who come across this in the future: reinstalling Python seems like a drastic step. Just deleting the `.pyc` files from whatever library is causing the `EOFError` was sufficient for me just now. – Danica May 26 '12 at 22:57

The EOFError: is most likely a race condition when 3 or more Python processes read/write the same pyc file. Fixed in Python 3.3: http://bugs.python.org/issue13146 – Guido van Rossum May 07 '16 at 02:21
@GuidovanRossum Thanks for the pointer! I've updated the answer. – phihag May 07 '16 at 08:13

try:
    import cookielib
except:
    import http.cookiejar
    cookielib = http.cookiejar

The cookielib module has been renamed to http.cookiejar in Python 3.0. The 2to3 tool will automatically adapt imports when converting your sources to 3.0.

Your answer would be more helpful if you presented one or two short examples. – O. Jones Jul 03 '17 at 21:43

My initial guess is that you have a corrupted library file. Inside your Python installation, look at lib/python3.2/http/cookiejar.py and scroll down to the end. Mine (Python 3.2.2) ends in the save() method definition with

finally:
    f.close()

If you see anything else, your installation is probably broken and I'd recommend reinstalling it.
