To use the if-else in one line in Python, we can use the expression: a if condition else b. In this expression, a is evaluated if the condition is True. If the condition is false, then b is evaluated. Let us use this as an example. Syntax of if else in one line 1 2 3 4...

在实际的工作中,常见的机器学习处理的数据大概分成三种,一种是图像数据,图像数据通常是RGB三通道的彩色数据,图像上的每个像素由一个数值表示,这个其实比较容易处理;一种是文本数据,文本数据挖掘就是我们通常说的自然语言处理,文本数据首先是非结构化的,同时我们需要把文本数据表示成数值,这得花一些功夫;还有一种就是...
