AttributeError: 'NoneType' object has no attribute 'write'
You shouldn't be writing to the file in the
finally block as any exceptions raised there will not be caught by the
except bock executes if there is an exception raised by the try block. The
finally block always executes whatever happens.
Also, there shouldn't be any need for initialising the
file variable to
The use of
return in the
except block will not skip the
finally block. By its very nature it cannot be skipped, that's why you want to put your "clean-up" code in there (i.e. closing files).
So, if you want to use try:except:finally, you should be doing something like this:
try: f = open("file", "w") try: f.write('Hello World!') finally: f.close() except IOError: print 'oops!'
A much cleaner way of doing this is using the
try: with open("output", "w") as outfile: outfile.write('Hello World') except IOError: print 'oops!'
