Once you have no references left to the file objects (a traceback
would hold such a ref, for example), the Python memory manager will
delete them.

If your script managed to create interactively visible variables with
these files, you can ask for those with 'whos':

In [5]: a=file('release.py')

In [6]: b=file('release.pyc')

In [7]: whos file
Variable   Type    Data/Info
----------------------------
a          file    <open file 'release.py', mode 'r' at 0x8663578>
b          file    <open file 'release.pyc', mode 'r' at 0x84d2f50>
