---

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’)
