How to unlock file locked by pexif

Question

I'm using the PEXIF module to read and edit EXIF data in JPEG files. After reading a file's data I would like to rename the file, but by then it is locked and os.rename() throws a WindowsError.

import pexif, os
f = 'oldName.jpg'
img = pexif.JpegFile.fromFile(f)
print img.exif.primary.ExtendedEXIF.DateTimeOriginal
os.rename(f, 'newName.jpg')

How can I unlock the file?

Answer 1

Why not use fromFd instead:

f = 'oldName.jpg'
with open(f, "rb") as fd:
    img = pexif.JpegFile.fromFd(fd)
print img.exif.primary.ExtendedEXIF.DateTimeOriginal
os.rename(f, 'newName.jpg')

The file handle will be closed when the with block's scope ends, so the rename will work.
