Name
xreadlines
Synopsis
xreadlines(f)Accepts argument f, which must be a file
object or a file-like object with a readlines
method like that of file objects. Returns a sequence object
x that is usable in a
for statement or as the argument to built-in
functions such as filter.
x represents the same sequence of strings
as f
.readlines( ), but
x does so in a lazy way, limiting memory
consumption. xreadlines is to
readlines much like xrange is
to range.
