To make this a little clearer, here's an even simpler example:
>>> import os
>>> os.fdopen(0)
<_io.TextIOWrapper name=0 mode='r' encoding='UTF-8'>
>>> 1
__main__:1: ResourceWarning: unclosed file <_io.TextIOWrapper name=0 mode='r' encoding='UTF-8'>
1
>>>
rdmurray@hey:~/python/p32>
What is happening here is that the file returned by os.fdopen is assigned to _, and then when I enter '1' *it* gets assigned to _, and the file gets gced and closed. You can also see this directly:
>>> import os
>>> f = os.fdopen(0)
>>> f.close()
>>>
rdmurray@hey:~/python/p32>
I explain this at length because I didn't understand it until I played around with it.
@Brian: this isn't a crash. It is completely equivalent to pressing <ctl>D at the interactive interpreter prompt. |
