Consider this scenario (which I ran into in real life):
I want to open a text file and do a lot of processing on the lines
of that file.
If the file does not exist I want to take appropriate action, e.g.
print an error message and abort the program.
I might write it like this:
try:

At least this attempts to abstract the problem of iterating over a file
(or multiple files) into a library routine. I've used it a l

My thoughts is that if the "many lines of code" puts the except to far
from the try, then perhaps it would have made sense to factor out some
part there into a function.
Perhaps like:
try:
with open(FileName) as f:
for ln in f{
process(ln)
except FileNotFoundError:
print(f"F
