Usual rejoinder: is there any way to do it outside Python? (As far
as I know, there isn't although I'm happy to be wrong). If you haven't
already, try one of the platform-specific lists, since this is
really an OS-issue.
For a Python-ish solution, you might have a retries loop, which
kept trying and backing away for increasing periods of time until
it gave up or succeeded. Rough-and-ready and completely untested:
<code>
import shutil
import time
src = "c:/temp/temp.mdb"
dest = "c:/temp/temp2.mdb"
n_retries = 5
base_delay = 2
n_retry = 0
while n_retry < n_retries:
try:
shutil.copyfile (src, dest)
except IOError:
time.sleep (2 ** n_retry)
n_retry += 1
continue
else:
print "succeeded after", n_retry, "retries"
break
else:
print "failed after", n_retry, "retries"
</code>
