本文整理了Java中org.python.util.PythonInterpreter.<init>()方法的一些代码示例，展示了PythonInterpreter.<init>()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。PythonInterpreter.<init>()方法的具体详情如下：
包路径：org.python.util.PythonInterpreter
类名称：PythonInterpreter
方法名：<init>

PythonInterpreter.<init>介绍

[英]Creates a new interpreter with an empty local namespace.
[中]创建一个本地命名空间为空的新解释器。

代码示例

private PythonInterpreter createInterpreter(Map vars) {
  PythonInterpreter pi = new PythonInterpreter();
  Iterator it = vars.entrySet().iterator();
  while (it.hasNext()) {
    Map.Entry ent = (Map.Entry) it.next(); 
    pi.set((String) ent.getKey(), ent.getValue());
  }
  return pi;
}

private static synchronized PythonInterpreter initPythonInterpreter(String[] args, String pythonPath, String scriptName) {

      // the java stack traces within the jython runtime aren't useful for users
      System.getProperties().put("python.options.includeJavaStackInExceptions", "false");

      pythonInterpreter = new PythonInterpreter();
