PyDAP

PyDAP is a pure Python implementation of the Data Access Protocol (DAP, also known as OPeNDAP), enabling access to scientific data over the internet. It acts as both a client for accessing remote OPeNDAP servers and a server for making local data available via OPeNDAP. A key feature is lazy data evaluation, where data is downloaded on-the-fly as needed, conserving bandwidth and time. The library is actively developed and maintained by the OPeNDAP community.
