[det]py_add_lib_dir(+Dir)

[det]py_add_lib_dir(+Dir, +Where)

Add a directory to the Python module search path. In the second form, Where is one of first or last. py_add_lib_dir/1 adds the directory as last. The property sys:path is not modified if it already contains Dir.

Dir is in Prolog notation. The added directory is converted to an absolute path using the OS notation using prolog_to_os_filename/2.

If Dir is a relative path, it is taken relative to Prolog source file when used as a directive and relative to the process working directory when called as a predicate.

Compatibility: PIP. Note that SWI-Prolog uses POSIX file conventions internally, mapping to OS conventions inside the predicates that deal with files or explicitly using prolog_to_os_filename/2. Other systems may use the native file conventions in Prolog.
