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.
