Tcl Equivalents of Python Modules, a resource for Python programmers who have seen the light and are migrating Tcl, maps Python modules to equivalent Tcl packages. APN A cautionary note - the Tcl column is empty not because the functionality is unavailable, but because no one finds it worthwhile to complete the table!
DKF Also note that some of these modules make no sense for Tcl.
