learn python

一个好的集成开发环境，能很大地提高编程效率。所以，我得需要先找一个好的python 的开发工具。

eclipse +pyDev, 感觉还不错。我把安装过程的关键点，详细记录于本文，以便自己和读者日后重新安装的时候，别找不到北。

eclipse 是一个java的免费的IDE, 我安装的是 eclipse-SDK-3.2.1-win32.zip，123M

下载地址：http://www.eclipse.org/downloads/download.php

解压缩后，就算安装完毕了，是个绿色软件。运行eclipse.exe,和我最常用的delphi相比，第1印象eclipse很华丽，比3.1版本又好看了些。也许 java的另一个开发工具NetBeans 也能开发python，界面风格比eclipse更细腻些，但我没有找到相关的资料，就选eclipse吧。

在eclipse里开发python，还需要安装一个插件：PyDev，

下载地址：http://sourceforge.net/projects/pydev/

org.python.pydev.feature-1_2_4.zip 软件不大，3.2M

在delphi里，安装组件，一般是在component菜单里，eclipse里没有这个菜单。凭借vc和delphi的经验，调整环境的设置，一般是在project菜单里，eclipse 有project菜单，但没有相应的子菜单。

看了pydev的简介，原来是在eclipse的help菜单里，eclipse/help/software updates/Find and install...

选择 Search for new features to install

选择 New Local Site， 输入pydev.zip 解压缩后在本地硬盘上的目录。

然后，还需要再设置一下python解释器的位置，告诉eclipse，python.exe 在哪个目录下面。

选择 Window/Preferences ，在左边的列表里找到 Pydev/Interpreter -Python, 在右边的python interpreters 里输入你的python.exe，我的安装是c:\python25\python.exe

至此python的Ide安装完毕。试试吧。

新建一个 Pydev Project, 输入一个hello world,单步调试运行，效果见下图。

debug python step

断点设置是绿色小球，和delphi，vc的红色小球不一样。

需要双击才能设置断点，和delphi，vc的单击设置断点也不一样。

呵呵。我一般不用调试器，都是使用print+log+眼看。有兴趣的话，还可以试一试我开发的编辑器UliPad。可以从 http://wiki.woodpecker.org.cn/moin/UliPad 下载，需要安装wxPython。它是一个纯Python写的软件。

How to Use Python to Find the Zipf Distribution of a Text FileMar 05, 2025 am 09:58 AM

This tutorial demonstrates how to use Python to process the statistical concept of Zipf's law and demonstrates the efficiency of Python's reading and sorting large text files when processing the law. You may be wondering what the term Zipf distribution means. To understand this term, we first need to define Zipf's law. Don't worry, I'll try to simplify the instructions. Zipf's Law Zipf's law simply means: in a large natural language corpus, the most frequently occurring words appear about twice as frequently as the second frequent words, three times as the third frequent words, four times as the fourth frequent words, and so on. Let's look at an example. If you look at the Brown corpus in American English, you will notice that the most frequent word is "th

Image Filtering in PythonMar 03, 2025 am 09:44 AM

Dealing with noisy images is a common problem, especially with mobile phone or low-resolution camera photos. This tutorial explores image filtering techniques in Python using OpenCV to tackle this issue. Image Filtering: A Powerful Tool Image filter

Introduction to Parallel and Concurrent Programming in PythonMar 03, 2025 am 10:32 AM

Python, a favorite for data science and processing, offers a rich ecosystem for high-performance computing. However, parallel programming in Python presents unique challenges. This tutorial explores these challenges, focusing on the Global Interprete

How to Perform Deep Learning with TensorFlow or PyTorch?Mar 10, 2025 pm 06:52 PM

This article compares TensorFlow and PyTorch for deep learning. It details the steps involved: data preparation, model building, training, evaluation, and deployment. Key differences between the frameworks, particularly regarding computational grap

How to Implement Your Own Data Structure in PythonMar 03, 2025 am 09:28 AM

This tutorial demonstrates creating a custom pipeline data structure in Python 3, leveraging classes and operator overloading for enhanced functionality. The pipeline's flexibility lies in its ability to apply a series of functions to a data set, ge

Serialization and Deserialization of Python Objects: Part 1Mar 08, 2025 am 09:39 AM

Serialization and deserialization of Python objects are key aspects of any non-trivial program. If you save something to a Python file, you do object serialization and deserialization if you read the configuration file, or if you respond to an HTTP request. In a sense, serialization and deserialization are the most boring things in the world. Who cares about all these formats and protocols? You want to persist or stream some Python objects and retrieve them in full at a later time. This is a great way to see the world on a conceptual level. However, on a practical level, the serialization scheme, format or protocol you choose may determine the speed, security, freedom of maintenance status, and other aspects of the program

Mathematical Modules in Python: StatisticsMar 09, 2025 am 11:40 AM

Python's statistics module provides powerful data statistical analysis capabilities to help us quickly understand the overall characteristics of data, such as biostatistics and business analysis. Instead of looking at data points one by one, just look at statistics such as mean or variance to discover trends and features in the original data that may be ignored, and compare large datasets more easily and effectively. This tutorial will explain how to calculate the mean and measure the degree of dispersion of the dataset. Unless otherwise stated, all functions in this module support the calculation of the mean() function instead of simply summing the average. Floating point numbers can also be used. import random import statistics from fracti
