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)?

Answer 1

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

Answer 2

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

Answer 3

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.
