I wanted to ask for ways to test whether a path exists. I usually use
os.path.exists(), which does a stat call on the path and returns True
if it succeeds, or False if it fails (catches os.error). But stat

But at least put an underscore between the words (raw_data), or, if

(rawData).
file.truncate(X) will truncate the file to at most X bytes (i.e. leave
the first X bytes of the file and throw away the rest). Is there a way
to throw away, say, the first X bytes of the file, and leave the rest?
