PyFITS is a Python module for reading, writing, and manipulating FITS files. The module uses Python's object-oriented features to provide quick, easy, and efficient access to FITS files. The use of Python's array syntax enables immediate access to any FITS extension, header cards, or data items. The FITS module is written in Python for maintainability and portability and uses C-extension modules, Numeric and Record, for efficient access to the data. These and other features, and future developments are discussed in this paper.
