I'm a Python newbie, so bear with me :)

I created a file called test.py with the contents as follows:

```
test.py
import sys
print sys.platform
print 2 ** 100

```

I then ran `import test.py` file in the interpreter to follow an example in my book.
When I do this, I get the output with the import error on the end.

```

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named py

```

Why do I get this error and how do I fix it? Thanks!
