将GetStringLength函数的输入输出参数分别使用argtypes和restype单独进行声明。 例2:如对于下面的函数,输入输出皆为字符串指针,函数的功能是对于输入pStr1赋值为“StrIn”,对于输出返回一个指向字符串常量“strOut”的指针,其函数C语言的实现代码如下: 在Python中的调用代码如下: 在上面代码中,同样分别对输入输出参数进...
Strings can beconcatenatedto build longer strings using the plus sign and also they can bemultipliedby a number, which results in the continuous repetition of the string as many times as the number indicates. Also, if we want to find out thelengthof the string, we simply have to use thelen...

鸢尾花数据集的特点是包含了4个属性:sepal.length(花萼长度),sepal.width(花萼宽度)和petal.length(花瓣长度)和petal.width(花瓣宽度)。这些属性可以用来预测鸢尾花卉属于哪个种类。此外,鸢尾花数据集还包含了3个线性可分离的特征:sepal.Length-Petal.Width(花萼长度-花瓣宽度),sepal.Length-Sepal.Width(花萼长度-花...
