You can use difflib to give you a diff of the two strings:

:>>> print('\n'.join(difflib.unified_diff('abc', 'adc')))
---

+++

@@ -1,3 +1,3 @@

 a
-b
+d
 c
:>>>

The docs talk about lines, but difflib works on sequence. I use it a lot to find
differences within lines.

I am getting a files ID3 tags using eyed3, this part seems to work and I get expected values in this case myTitleName (Track name) is set to “Deadlock Holiday” and myCompareFileName is set to “01 Deadlock Holiday” (File Name with the Track number prepended). The is digit test works and myCompareFileName is set to  “Deadlock Holiday”, so they should match, right?
