Can anyone comment as to whether this is good style: try: f=open(fname,'rb').read() except: ... error message ...
------- vs. --------- import os.path if os.path.isfile(fname): f=open(fname,'rb').read() else: ... error message ... I much prefer the first example because it's so much easier and quite robust. I figure I still have to do the try when opening the file, even in the 2nd case. Am I paying a performance penalty for having my cake and eating it?
