简明 Python 教程
http://www.woodpecker.org.cn:9081/doc/abyteofpython_cn/chinese/index.html
学习编程快20年了,很少见到如此好的教程。简单,清晰。大部分的软件书籍翻译的是呕呀啁咂难为听,名声显赫的译者如候某人,也是50步笑百步而已。
网上有一种说法,一个有经验的程序员可以在半天内,学会python。
我试了一下,感觉该说法有点夸张。我大概用了1个晚上(3个小时)看到了《简明 Python 教程》第9章,感到这章有点难度了,头也有点晕了,语法基本上也看完了,就去休息。
准备第2天再慢慢看,用1-2个星期的下午时间,肯定是能学会的。
然后,我会把python和c++,delphi的使用感觉做一个对比。
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。
python自己带的IDLE (Python GUI) 整体感觉还不错。
因为很久没有用过解释语言的开发环境了。用IDLE输入《简明 Python 教程》里边带的几个小例子,感觉比较新奇,好象又回到了上中学时在6502的计算机上,输入basic语言的体验。
调试怎么用呀?有点怪异,比较难上手,到现在也不会用,也不需要会了,因为现在我用eclipse +pyDev。
所以当大概学会python的语法后,我第1想到的是,先找一个更顺手的IDE。如果没有方便的IDE,宁可不学python。
上网先看到了boa constructor,免费的python ide,据说类似与delphi,居然这么好?赶快下来用,用后感觉比较失望。首先看到一个很难看的兰色的大蟒蛇,窗口的布局有些怪异,和delphi是不太一样的。单步调试的时候,屏幕有闪动,好象还有一些BUG,在我这里调试时,单步运行的感觉不太好。又换了winpdb, 感觉更不好。
然后,换 eclipse +pyDev, 感觉还不错。安装过程,请见下文分解。
