在eclipse开发环境下python中怎么引用函数
推荐回答(2个)
选中需要查看的函数(光标移到函数所在的位置),然后使用eclipse快捷键Ctrl+Shift+G,然后就会在search窗口中看到函数调用的树状结构图。
以最简单的一个代码为例:
class A:
s="hello"
def p(self):
print(self.s)
if __name__ == '__main__':
a=A()
a.p()
光标移到第4行p的位置,然后Ctrl+Shift+G,得到如下所示:
前言
笔者最近迷上了Python,但是一直没有找到满意的IDE。虽然使用Vim编辑器+命令行的方式比较酷,然而一个优秀的IDE确实能让开发速度提升不少。于是笔者想到Eclipse——一个神一样的利器。经过一番曲折,终究修成正果。整理成文,希望对热爱的Python的童鞋有所帮助。

首先我们需要明白一点——Eclipse作为一个灰常优秀的开发工具,它可被用作N多语言的IDE,然而前提是我们需要安装对应的编译器或者解释器。比如常见的Java开发,就必须JDK。因此要用Eclipse进行Python开发也必须Python的“JDK”,即Python解释器。笔者已安装Python2.7版本的解释器,在本文便Python2.7为示例分步骤说明搭建过程。
基本需求:
·1 Eclipse(版本不要太陈旧)
·2 Python解释器(www.python.org)
步骤1:
下载用于在Eclipse中开发Python的插件PyDev。
文件名:org.python.pydev.feature-1.6.1.2010080312.zip。
下载地址:http://sourceforge.net/projects/pydev/files/
步骤2:
解压org.python.pydev.feature-1.6.1.2010080312.zip。将解压后的features和plugins文件夹中的内容拷贝到Eclipse安装目录下相同的文件夹中即安装PyDev插件成功。
步骤3:
打开Eclipse(如果已经打开,则重启Eclipse)。选择window——》Presences,设置如图:
展开PyDev,选择Interpreter - Python,单击New...按钮,在弹出的Select interpreter窗 口中单击Browse...按钮,找到已经安装的Python解释器。单击Select interpreter窗口中 单击OK按钮,在弹出的Selection Needed窗口中单击Select All按钮,然后单击OK按 钮完成设置。然后在Preferences窗口中选择Apply——》OK完成设置。如图:
以下几步Python 3.x必选,Python 2随意。我比较习惯Unicode,所以一次性在这儿设定了。
2、General->Editors->Text Editors->Spelling,Encoding改成Other:UTF-8
3、General->Workspace,Text file encoding改成Other:UTF-8
4、找到安装目录下的\plugins\org.python.pydev.debug_x.x.x.yyyymmddhh\pysrc\pydevd.py,
920行的 encoding = Non 改成 encoding = "UTF-8",保存
至此,PyDev的配置就完成了。
步骤4:
选择File——》New——》Other。在弹出的New窗口中,按下图操作:
步骤5:
在弹出的窗口中,依次填写Project name(工程名)——》为工程选择Directory(目录)——》选择Project type(工程类型)——》选择版本号(如果没有自己正在使用的版本号,则选择比自己版本号老一些的版本号)——》选择Interpreter(解释器)——单击Finish按钮完成设置。如图:
步骤6:
现在可以在已创建的工程中新建模块了,如图:
我们在src包中建立一个空的HelloWorld模块,如图:
步骤7:
按下图所示,编写一个简单的HelloWorld脚本并运行之。
