第 2 章 Python 直譯器
jython 直譯器
在安裝過程（參閱前面的「安裝 Jython」）中建置的
jython
直譯器，執行方
式類似於
python
程式：
[path]jython {options} [ -j jar | -c command | file | - ] {args}
-j
jar
告訴 Jython 要執行的主要指令稿是那個
.jar
檔案中的
__run__.
py
。選項
-i

-S
和
-v
的意義都與
python

--help
就像是
python

-h
，而
--version
就像
python
的
-V
。
jython
不使用環境變數，而是使
用安裝目錄中一個名為
registry
的文字檔，以結構化的名稱來記錄特性
（properties）。舉例來說，
python.path
這個特性對Jython 來說，就等
同於 Python 的環境變數
PYTHONPATH
。你也能使用
jython
命令列選項
-D
name=value
來設定特性。
