Using ExifRead on reapting filenames

JaredPilbeam2

Hello,

I have a lot of JPEGs in a Windows directory. In most cases these JPEGs do not have similar filenames. On the other hand, there are some repeats:

Using exifread, I'm appending the 'date taken' to the end of the seven digit number of the filenames. This script gets me close, but it's not exactly doing what I want. It skips the files with similar names (e.g. 7400010 (2), 7400010b). Also, after running the script I'm having trouble avoiding the '.' of the file extension. Ideally, I'd like every filename to have this structure: 7400010_2018-04-25. And as far as the files with similar names goes, how do I preserve the (2) and the b?

Another approach, just testing file names:

fn = [ '7400010 (2).jpg',
       '7400010.jpg',
       '7400015b.jpg' ]

for f in fn:
    print f[:-4].replace(' ','_').replace('(','').replace(')','').replace('.','') + '_' + 'date'

# prints

I had a script that did a similar rename. I made a few changes to work in my earlier comment. I had used the exif tag 'Image DateTime', but it should work with 'EXIF DateTimeOriginal'. You want to add error checking to insure that the exif tag is valid. If you have multiple directories, then use os.walk. Just another approach; hope it helps.

Python strings are case sensitive:

>>> 'file.jpg'.endswith('.JPG')
False

Maybe try:

>>> 'file.jpg'.endswith(('.JPG', '.jpg'))
True

Randy,

that works nice, but is it possible to put the whole directory into a list?

JaredPilbeam2

Joshua,

that appended JPG to the end of the date and skipped the repeats:

Another approach, just testing file names:

fn = [ '7400010 (2).jpg',
       '7400010.jpg',
       '7400015b.jpg' ]

for f in fn:
    print f[:-4].replace(' ','_').replace('(','').replace(')','').replace('.','') + '_' + 'date'
