What are your needs, that are not covered by Python's csv module?
You have this comment near the beginning of your source file:
"This File contains classes, which enable you to get mor efficient
access to
    csv - files."
How do you define efficiency? Speed of reading files? Last time I
looked, the guts of the Python csv module was written in C. Memory
footprint? Try sucking in a file with a few million records with your
module and check the memory usage.

What errors did you get when you tried to use the Python module?
