在Python shell中输入import this就会在屏幕上打印出来Python的设计哲学,如下: In [25]: import this The Zen of Python, by Tim Peters Beautiful is better than ugly. Explicit is better than implicit. Simple is better than complex. Complex is better than complicated. Flat is bet…
Python的设计哲学--zen of Python Beautiful is better than ugly. 优美胜于丑陋 Explicit is better than implicit. 明了胜于晦涩 Simple is better than complex. 简单胜过复杂 Complex is better than complicated. 复杂胜过凌乱 Flat is better than nested. 扁平胜于嵌套 Sparse is better…
Beautiful is better than ugly. 优美胜于丑陋 Explicit is better than implicit. 明了胜于晦涩 Simple is better than complex. 简单胜过复杂 Complex is better than complicated. 复杂胜过凌乱 Flat is better than nested. 扁平胜于嵌套 Sparse is better than dense. 间隔胜于紧凑 Readability counts.…
目录 ndarray是什么 ndarray的设计哲学 ndarray的内存布局 为什么可以这样设计 小结 参考 博客:博客园 | CSDN | blog 本文的主要目的在于理解numpy.ndarray的内存结构及其背后的设计哲学. ndarray是什么 NumPy provides an N-dimensional array type, the ndarray, which describes a collection of "items" of the same type. Th…
算法题 已知整型数值 a[99], 包含的所有99个元素都是从1-100中随机取值,并且这99个数两两互不相等,也就是说从1到100这100个数字有99个在数值内,有一个缺失.请设计一个算法将缺失的数字找出来. #!/usr/bin/python import random rand_num=[] x=0 while len(rand_num) != 99: rand_one=random.randint(1,100) if rand_one not in rand_…
昨天看了这篇文章 <关于Unix哲学> 首先用了两个例子,用风扇吹出空肥皂盒 和 太空铅笔,来说明简单设计也能派上作用吧. Unix哲学,Wikipedia上列出了好几个版本,不同的人有不同的总结.发明管道命令的Doug McIlroy总结了三条,而Eric S. Raymond则在The Art of Unix Programming一书中,一口气总结了17条. 但是所有人都同意,"简单原则"----尽量用简单的方法解决问题----是"Unix哲学"的…
