在Python中,索引可以是负数,-1表示最后一个元素(倒数第一),-2表示倒数第二个元素; 例如: 通用序列操作 索引(indexing)、分片(sliceing)、加(adding)、乘(multiplying),判断某个元素是否属于该序列成员、此外,还有计算序列长度,找出最大或最小元素的内建函数; ...
In Python, the interpreter modifies (mangles) the class member names starting with __ (double underscore a.k.a "dunder") and not ending with more than one trailing underscore by adding _NameOfTheClass in front. So, to access __honey attribute in the first snippet, we had to append _Yo...
本节介绍另一项任务:回归。这里,我们有格式为d= {(x1,y1),(x2,y2),…(xn,y的数据 我们的任务是生成一个计算程序,实现函数f:x→y。 注意,与二进制分类中的二进制分类标签y= 1 不同,我们使用实值预测。我们用看不见的数据的均方根误差(RMSE)来衡量这个任务的性能 ...
>>> odd = lambda x : bool(x % 2) >>> numbers = [n for n in range(10)] >>> numbers[:] = [n for n in numbers if not odd(n)] # ahh, the beauty of it all >>> numbers [0, 2, 4, 6, 8] Common Mistake #6: Confusing how Python binds variables in closures Considerin...
