Your file record requires at least two objects in addition to the line itself: the FileRecord instance and the dictionary instance (__dict__) used to hold its attributes. You can use a new style class with __slots__ to omit that dictionary:

class FileRecord(object): __slots__ = ['line'] def __init__(self, line): self.line = line

or defer instance creation:

class FileRecords(list): # store here all the lines, maybe using readlines() def __getitem__(self, index): return FileRecord(list.__getitem__(self, index))
