当我尝试将csv文件导入数据帧时,pandas(0.13.1)忽略了dtype参数.有没有办法阻止大熊猫自己推断数据类型?
我正在合并几个CSV文件,有时客户包含字母和pandas导入为字符串.当我尝试合并两个数据帧时,我得到一个错误,因为我正在尝试合并两种不同的类型.我需要存储为字符串的一切.
数据片段:

代码中是否有错误或其他方法?
Sub AddBorders()

x = originX + radius*Cos(角度);
y = originY + radius*Sin(角度);
为什么这些点不能均匀分布在圆的边缘?
结果图:

class Circle
{
public Vector2 Origin { get; set; }
public float Radius { get; set; }
