rename files to match their EXIF “Date Taken”?

jpilbeam

I need some help putting the date in the filenames. Here's the working code I have so far. 

<SPAN class="keyword token">import</SPAN> arcpy<SPAN class="punctuation token">,</SPAN> sys
<SPAN class="keyword token">import</SPAN> exifread
<SPAN class="keyword token">from</SPAN> exifread <SPAN class="keyword token">import</SPAN> exif
<SPAN class="keyword token">import</SPAN> os
<SPAN class="keyword token">import</SPAN> time
<SPAN class="keyword token">from</SPAN> datetime <SPAN class="keyword token">import</SPAN> datetime

im <SPAN class="operator token">=</SPAN> r<SPAN class="string token">"path\to\DOT_SignInventory"</SPAN>

<SPAN class="keyword token">for</SPAN> root<SPAN class="punctuation token">,</SPAN> dirnames<SPAN class="punctuation token">,</SPAN> filenames <SPAN class="keyword token">in</SPAN> os<SPAN class="punctuation token">.</SPAN>walk<SPAN class="punctuation token">(</SPAN>im<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">:</SPAN> <SPAN class="comment token">#iterate directory</SPAN>
    <SPAN class="keyword token">for</SPAN> fname <SPAN class="keyword token">in</SPAN> filenames<SPAN class="punctuation token">:</SPAN>
        <SPAN class="keyword token">if</SPAN> fname<SPAN class="punctuation token">.</SPAN>endswith<SPAN class="punctuation token">(</SPAN><SPAN class="string token">'.JPG'</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">:</SPAN>

                exif <SPAN class="operator token">=</SPAN> exifread<SPAN class="punctuation token">.</SPAN>process_file<SPAN class="punctuation token">(</SPAN>image<SPAN class="punctuation token">)</SPAN>
                dt <SPAN class="operator token">=</SPAN> str<SPAN class="punctuation token">(</SPAN>exif<SPAN class="punctuation token">[</SPAN><SPAN class="string token">'EXIF DateTimeOriginal'</SPAN><SPAN class="punctuation token">]</SPAN><SPAN class="punctuation token">)</SPAN> <SPAN class="comment token">#get 'Date Taken' from JPG</SPAN>
                ds <SPAN class="operator token">=</SPAN> time<SPAN class="punctuation token">.</SPAN>strptime<SPAN class="punctuation token">(</SPAN>dt<SPAN class="punctuation token">,</SPAN> <SPAN class="string token">'%Y:%m:%d %H:%M:%S'</SPAN><SPAN class="punctuation token">)</SPAN>
                nt <SPAN class="operator token">=</SPAN> time<SPAN class="punctuation token">.</SPAN>strftime<SPAN class="punctuation token">(</SPAN><SPAN class="string token">"%m/%d/%Y"</SPAN><SPAN class="punctuation token">,</SPAN>ds<SPAN class="punctuation token">)</SPAN><SPAN class="comment token">#variable with 'Date Taken'</SPAN>
                <SPAN class="keyword token">print</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="string token">"Photo:{} Date Taken:{}"</SPAN><SPAN class="punctuation token">.</SPAN>format<SPAN class="punctuation token">(</SPAN>fname<SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"_"</SPAN> <SPAN class="operator token">+</SPAN> nt<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">)</SPAN>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

I've tried these couple things after the print statement, but no cigar:

new_file <SPAN class="operator token">=</SPAN> fname <SPAN class="operator token">+</SPAN> nt <SPAN class="operator token">+</SPAN> <SPAN class="string token">".jpg"</SPAN>‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN></SPAN>

f <SPAN class="operator token">=</SPAN> open<SPAN class="punctuation token">(</SPAN>fname<SPAN class="punctuation token">.</SPAN>format<SPAN class="punctuation token">(</SPAN>nt<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"w"</SPAN><SPAN class="punctuation token">)</SPAN>
f<SPAN class="punctuation token">.</SPAN>write<SPAN class="punctuation token">(</SPAN>fname <SPAN class="operator token">+</SPAN> nt<SPAN class="punctuation token">)</SPAN>
f<SPAN class="punctuation token">.</SPAN>close‍‍‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

You will also need to close the file before renaming it.  Perhaps:

for root, dirnames, filenames in os.walk(im): #iterate directory
    for fname in filenames:
        if fname.endswith('.JPG'):
            with open(os.path.join(root, fname), 'rb') as image: #file path and name
                exif = exifread.process_file(image)
                dt = str(exif['EXIF DateTimeOriginal']) #get 'Date Taken' from JPG
                ds = time.strptime(dt, '%Y:%m:%d %H:%M:%S')
                nt = time.strftime("%Y-%m-%d",ds)
                newname = fname[0:7] + "_" + nt + ".jpg"
            image.close()
            os.rename(os.path.join(root,fname), os.path.join(root,newname))<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>
