以上代码中,我们定义了一个名为truncate_float()的函数,该函数接受两个参数:num为要进行截断的浮点数,decimal_places为要保留的小数位数。函数内部通过将浮点数拆分为整数部分和小数部分,然后截断小数部分,并将结果返回。 使用示例: 代码语言:txt 复制 num = 3.141592653589793 decimal_places = 3 result = trunc...

树形图Tree diagram (代码下载) 本文旨在描述如何使用Python实现基本的树形图。要实现这样的树形图,首先需要有一个数值矩阵。每一行代表一个实体(这里是一辆汽车)。每列都是描述汽车的变量。目标是将实体聚类以了解谁与谁有共同点。python下通过scipy中hierarchy.linka
