Python 3.3 - urllib.request - import error

Question

When I try to run the following Python 3.3 code on OS X 10.8 in PyCharm 2.7 (or run the .py file with the Python 3.3/2.7.3 launcher):

import urllib.request
f = urllib.request.urlopen('http://www.python.org/')
print(f.read(300))

I get the following error message:

/System/Library/Frameworks/Python.framework/Versions/3.3/bin/python3 /Users/username/PycharmProjects/urllib/urllib.py
Traceback (most recent call last):
  File "<frozen importlib._bootstrap>", line 1512, in _find_and_load_unlocked
AttributeError: 'module' object has no attribute '__path__'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/Users/username/PycharmProjects/urllib/urllib.py", line 3, in <module>
    import urllib.request
  File "/Users/username/PycharmProjects/urllib/urllib.py", line 3, in <module>
    import urllib.request
ImportError: No module named 'urllib.request'; urllib is not a package

Process finished with exit code 1

The only way I can succesfully run the code is via the Python shell.

Any ideas on how to solve this?

Thanks.

I changed the filename to url.py, now it succesfully executes in PyCharm.

But when executing the file via Python Launcher 3.3 it gives me the following error:

 File "/Users/username/PycharmProjects/urllib/url.py", line 3, in <module>
import urllib.request
ImportError: No module named request

Why is the code running fine in PyCharm (3.3) but giving me an error when launched with Python Launcher (3.3)?

By default Python searches the current directory first for modules to import. — mechanical_meat, Apr 04 '13 at 20:54

You named your file urllib, it is shadowing the standard library package. Rename your file.

I have no idea what "Python Launcher" is. Does it use python3? Do you have an `__init__.py` file? Can your project (it's also named urllib) shadow the `urllib` package? – Pavel Anossov Apr 04 '13 at 21:05
On OS X the Python Launcher is the app that launches/runs your *.py file. Solved the problem by deleting the url.pyc file using http://stackoverflow.com/questions/514371/whats-the-bad-magic-number-error Thanks for you help Pavel! – narzero Apr 04 '13 at 21:13

In mac, VSCode is using Python 2. If you print urllib module, you will find out that this module is for Python 2.

So, I added one comment to choose Python version:

#!/usr/local/bin/python3
from urllib.request import urlopen

In my case, it waw solved activating in command palette (shift+commant+p) Linting: Enable Linting: on and in VMStudio Settings (Preferences => Settings) select flake8 in Python:linter => Linter to use as flake8.
