Pythonic way of reading a textfile line by line without throwing an exception

[Matimus]

> fp=open(filename, 'r')
> for line in fp:
>     # do something with line
>
> fp.close()

Or, if you are using Python 2.5+, you can use the file context via the
`with' statement.

[code]
from __future__ import with_statement # this line won't be needed in
Python 2.6+

with open(filename, 'r') as fp:
    for line in fp:
        # do something with line
[/code]

This basicly just closes the file automatically (even if there is an
exception) when the context (part indented under `with') is exited.
This is a new feature, but probably the most pythonic way of doing it.
That will be especially true in the future.
