"The vocab " { $vocab-link "python.syntax" } " implements a higher level factorific interface on top of the lower-level constructs in this vocab. Prefer to use that vocab most of the time."
{ $notes "Sometimes the embedded python interpreter can't find or finds the wrong load path to it's module library. To counteract that problem it is recommended that the " { $snippet "PYTHONHOME" } " environment variable is set before " { $link py-initialize } " is called. E.g:" }
