I would make a smart iterator that distinguishes between a file and a
string. For example (untested):
def lineIter(fileOrString):
if isinstance(fileOrString, file):
return iter(fileOrString)
return iter(fileOrString.splitlines())
Now you can say
for item in lineIter(block):
and get lines whether block is a file or a string.
Note that lines returned from a file will include newlines while those
from a string will not.
