I would like to suggest an alternative syntax, that will, in a sense, apply
the best of both worlds:

with open('sample_data/README.md') as f:

except FileNotFoundError:
 logging.error("File not")

Are you aware that in the case of a `FileNotFoundError`
no context manager is created (the context manager is the `f`
in your code).

Why not use:
try:
  with open()...
    ...
except FileNotFoundError:
  ...


I do not think that your use case requires a `with` extension.
