The first thing to introduce is the Python Imaging Library, using the following methods:
Copy Code code as follows:
From PIL import Image
From PiL. Exiftags Import TAGS
def get_exif_data (fname):
"" "Get embedded EXIF data from image file." "
ret = {}
Try
img = Image.open (fname)
If Hasattr (IMG, ' _getexif '):
Exifinfo = Img._getexif ()
If Exifinfo!= None:
For tag, value in Exifinfo.items ():
decoded = Tags.get (tag, tag)
Ret[decoded] = value
Except IOError:
print ' IOError ' + fname
return ret
if __name__ = = ' __main__ ':
FileName = ' c:/users/leyond/desktop/img_20121122_153514.jpg '
EXIF = Get_exif_data (fileName)
Print EXIF
The list returned is as follows:
Copy Code code as follows:
Exifversion

Exifimagewidth
Datetimeoriginal
Datetimedigitized
Exifinteroperabilityoffset
Flashpixversion
Meteringmode
LightSource

59932 of them, is a large string of hexadecimal characters, do not know why. In addition to PIL, there are many class libraries to use:
Media Metadata for Python
exif.py
Python Exif Parser
A Blogger ' s Exif Parser
Pyexiv2
Then look at the exif.py, the use of the method is very simple: exif.py img_20121122_153514.jpg

As for the Python Exif Parser, it seems like it hasn't been updated for a long time, and the usage is similar:
Copy Code code as follows:
Import EXIF
Photo_path = "Somepath\to\a\photo.jpg"
data = Exif.parse (Photo_path)
Other libraries please study for yourself.
