is_integer, is_digit 表达式和操作符 变量和基本表达式 1. 变量在第一次创建时赋值 2. 变量在表达式中使用将被替换为它们的值 3. 变量在表达式中使用以前必须被赋值 4. 变量像对象一样不需要在一开始进行声明 也就是说,这些赋值会让变量a和b自动生成: ...
In this chapter, I am mainly concerned with time series in the first three categories, though many of the techniques can be applied to experimental time series where the index may be an integer or floating-point number indicating elapsed time from the start of the experiment. The simplest and...
