Re^5: What technical benfits perl offers over python + few more questions.

I think the distinction being made is maybe that in (say) Java trying to print on a closed filehandle object would throw an IOException which your code would be required to handle, whereas perl -E 'close(STDOUT);say qq{FOOP}' will run (producing no output but also not printing any sort of error (although you could check the return from say and print $!)).

Of course if you "`use warnings;`", you will see the "print() on closed filehandle STDOUT" warning.	[reply] [d/l]

Actually I think I had the right intuition with Python. They use exceptions for non-fatal communications like in https://softwareengineering.stackexchange.com/questions/112463/why-do-iterators-in-python-raise-an-exception Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply]

I see what you mean. I am just starting with Python. Instead of handling the exception, it appears that: `for value in some_iterable: print(value)` [download] is the preferred syntax.	[reply] [d/l]
