Use "with suppress()" to suppress python exceptions

Using
```Python
with suppress(OSError):
    os.remove('somefile.tmp')
```
instead of
```Python
try:
    os.remove('somefile.tmp')
except OSError:
    pass
```
makes the code more compact and more readable IMO.

This pattern was recommended by Raymond Hettinger, a Python Core
Developer in his talk "Transforming Code into Beautiful, Idiomatic Python" at https://www.youtube.com/watch?v=OSGv2VnC0go. The transcript is available at https://github.com/JeffPaine/beautiful_idiomatic_python
