将 turtle pos() 添加到 array/matrix/variable

Question

我想知道是否可以将 pos()（乌龟 python）添加到向量或变量中，例如，如果输出 pos() 或 [ 23,12] 并将其保存为 [23,12]（矩阵 Python）或 n = 23 和 m = 12.

谢谢

Answer 1

turtle.pos 的文档说

turtle.pos()
Return the turtle’s current location (x,y) (as a Vec2D vector).

然后转到 turtle.Vec2D 文档

turtle.Vec2D(x,y)
A two-dimensional vector class, used as a helper class for implementing turtle graphics. May be useful for turtle graphics programs too. Derived from tuple, so a vector is a tuple!

所以它基本上表现得像 tuple。如果你想把它转换成别的东西，你可以做类似

的事情

a = list(turtle.pos())          # list of values
b = numpy.array(turtle.pos())   # numpy array of values

Vec2Dclass具有其他容器所没有的操作，即仿射几何操作，如加、减、内（点）积、向量-标量乘法等

将 turtle pos() 添加到 array/matrix/variable

Add turtle pos() to a array/matrix/variable
