I think I found a decently short solution for part 2 in python:
Looks very elegant! I'm having trouble understanding how this finds digit "words" from the end of the line though, as they should be spelled backwards IIRC? I.e.
eno
,owt
,eerht
It simply finds all possible digits and then locates the last one through the reverse indexing. It’s not efficient because there’s no shortcircuiting, but there’s no need to search the strings backwards, which is nice. Python’s startswith method is also hiding a lot of that other implementations have done explicitly.
