can you be a bit more precise? are we talking about text files or
binary files? how do you want to treat any newlines that actually
appear in the file?

I believe the OP is referencing this behavior:

for line in file('x.txt'):
assert not (
line.endswith('\r') or
line.endswith('\n')), "Don't want this"
else:
yay() # we never end up reaching this

which can be done with a simple generator/wrapper:

def unnewline(iterator):
for line in iterator:
yield line.rstrip('\r\n')
for line in unnewline(file('x.txt')):
assert not (
line.endswith('\r') or
line.endswith('\n')), "Don't want this"
else:
yay() # we get here this time

Alternatively, the content can just be modified on the fly:

for line in file('x.txt'):
line = line.rstrip('\r\n')
...

yes, the interpretation would differ if it were a binary file,
but the above interpretation is a pretty common case (i.e. I
encounter it daily, in my processing of client data-feeds).
