Sure! It's the kind of thing you can easily find on Python's docs,
OR by playing around in an interactive session -- let's try the
latter, as it's more fun...:
>>> f = file('some file name', 'w')
['__class__', '__delattr__', '__doc__', '__getattribute__', '__hash__',
'__init__', '__iter__', '__new__', '__reduce__', '__repr__', '__setattr__',
'__str__', 'close', 'closed', 'fileno', 'flush', 'isatty', 'mode', 'name',
'read', 'readinto', 'readline', 'readlines', 'seek', 'softspace', 'tell',
'truncate', 'write', 'writelines', 'xreadlines']
Hmmm, that "name" thing looks interesting -- let's see:
'some file name'
Oh well, so much for the fun -- it was clearly far too easy to find
this time, for it to be any fun at all. Still, it IS a good approach
to keep in mind -- sometimes it's very fast, like here, other times
it can be quite a bit of fun. Of course, Python's documentation and
the many excellent books about Python you can read (both paper and
on-line ones, both free and for-pay) offer an alternative, too, if
you LIKE reading the fine manuals.
