contextlib.suppress in Python

Returns a context manager that suppresses the specified types of exceptions.

contextlib.suppress (* exceptions)

* exceptions - Types of exceptions that should be ignored. 


Returns a context manager that will suppress the specified types of exceptions if they occur in during the execution of the instruction body with , while execution will continue from the code following the instruction.

Attention

Like any other mechanism for suppressing exceptions , the context manager mentioned should only be used in a very limited set of scenarios, when it is absolutely clear that program execution must continue.


  import os 
from contextlib import suppress

with suppress (FileNotFoundError):
os.remove (`somefile.tmp`)

# Equivalent:
try:
os.remove (` somefile.tmp`)
except FileNotFoundError:
pass

The created manager object is reentrant . This means that within the same with block, which has the same nested blocks, it can be used several times:

  import os 
from contextlib import suppress

remove_error_supressed = suppress (FileNotFoundError)
with remove_error_supressed:
os.remove (`somefile.tmp`)

with remove_error_supressed:
os.remove (`anotherfile.tmp`)
