I want to delete the file
filename if it exists. Is it proper to say
if os.path.exists(filename): os.remove(filename)
Is there a better way? A one-line way?
A more pythonic way would be:
try: os.remove(filename) except OSError: pass
Although this takes even more lines and looks very ugly, it avoids the unnecessary call to
os.path.exists() and follows the python convention of overusing exceptions.
It may be worthwhile to write a function to do this for you:
import os, errno def silentremove(filename): try: os.remove(filename) except OSError as e: # this would be "except OSError, e:" before Python 2.6 if e.errno != errno.ENOENT: # errno.ENOENT = no such file or directory raise # re-raise exception if a different error occurred
