I am not sure this is a duplicate since the other issue was about newline at
the end of strings. This is about the diff being little irrelevant even with
newline in the end for strings. Sample program where change in 5th character
gives the reported diff.
import difflib
for i in range(7):
print(f"Change character at {i}")
a = list("drwxrwxr-x 2 2000 2000\n")
b = "drwxrwxr-x 2 2000 2000\n"
a[i] = '-'
a = ''.join(a)
print(''.join(difflib.ndiff([a], [b])))
Change character at 0
