Python编程语言在使用的时候需要和很多种编程语言进行融合。Java就是一个和Python编程语言接触最多的一个编程语言。下面我们就来看一看在Java中如何进行Python编程语言的调用。
- python.java
- import java.util.List;
- import org.python.core.PyException;
- import org.python.core.PyInteger;
- import org.python.core.PyObject;
- import org.python.util.PythonInterpreter;
- public class python {
- public static void main(String []args)throws PyException
- {
- PythonInterpreter interp =new PythonInterpreter();
- System.out.println("Hello, brave new world";
- interp.exec("import sys";
- interp.exec("print sys";
- interp.set("a", new PyInteger(42));
- interp.exec("print 'test='+str(a)";
- interp.exec("x = 2+2";
- PyObject x = interp.get("x";
- System.out.println("x: "+x);
- System.out.println("Goodbye, cruel world";
- interp.exec("import re";
- interp.exec("t =re.compile('^(0{2})IFCSUM)MANIFEST):')";
- interp.exec(" a = t.search('00:IFCSUM:MANIFEST:').groups()";
- PyObject k = interp.get("a");
- List list = ((List)k.__tojava__(List.class));
- //System.out.println(k);
- System.out.println(list);
- }
- }
以上就是对Python编程语言在Java中的具体应用。
