Python errors with simple code

Question

I feel embarrassed just writing this question.

I've just installed python 3.4 and django 1.8

If I enter the python interpreter and enter:

>>> import django    
>>> print(django.get_version())

I get the answer 1.8 which is fine.

If I create a file django.py and in it enter:

import django
print(django.get_version())

Two things happen:

When I run it I get the error

Traceback (most recent call last):
  File "django.py", line 1, in <module>
    import django
  File "C:\Python_Mongo\django.py", line 2, in <module>
    print(django.get_version())
AttributeError: 'module' object has no attribute 'get_version'

It then creates a cache folder __pycache__ and if I simply start python interpreter and enter the command: import django it runs my django.py file! (any other command is fine).

Please help :(

You have a file django.py in your local directory, it masks the Django package. Rename it to something else.

See your traceback:

  File "django.py", line 1, in <module>
    import django

Note how the line import django is run from a file named django.py?

ah, how embarrassing :), something I never thought of. btw, thanks for the edit, stackoverflow editor was driving me crazy with >>> removing itself and '2.' changing itself to '1.' on rendering

@Neil: > is syntax for a blockquote, and lists auto-number, but if the list sequence is broken the numbering starts at 1 again.

There is nothing surprising. If you invoke the import anything in a file named anything.py it will import itself.

Python's import path resolving searches current directory first and only after it looks for the module in system path.
