readline

Synopsis

                        f.readline(size=-1)

Reads and returns one line from f’s file, up to the end of line (\n) included. If size is greater than or equal to 0, readline reads no more than about size bytes. In this case, the returned string may not end with \n. \n may also be absent if readline reads up to the end of the file without finding \n. readline returns an empty string only if the file’s current position is at the end of the file or if size equals 0.
