Python: with statement and execption handling

Question

I give following code snippet, As at the end of the code I am getting blank output file

in with context when exception is raised The file is closed and again overridden in next iteration

with open('output', 'w') as f:
    try:
        for i in range(1, 100):
             if i % 2 == 0:
                 f.write('%d \n' % i)
             else:
                 raise Exception()
    except Exception as e: 
        pass

Is my understanding correct? If so, Why this behavior is there?As I am handling the exception.

Is it right that with statement will always close files whenever exception is raised in side block.

What could be possible solution using with statement?

Answer 1

When using a try/except block, the try block is not continued upon completion of the except block.

A possible solution would be to replace the raise Exception() statement - which is currently raising a meaningless exception - with a pass statement instead.

In fact, you should probably do a little reading regarding when to use exceptions.
