Python中的turtle.pos()方法
Turtle 模块以面向对象和面向过程的方式提供Turtle图形基元。因为它使用 Tkinter 作为底层图形，它需要安装一个支持 Tk 的 Python 版本。 turtle.pos()该方法用于查找Turtle的当前位置（x, y），是一个Vec2D-向量。这个方法的别名是：pos | position。 语法： turtle.pos() or turtle.position() 返回：turtle的当前位置（x，y）坐标。 该函数不需要任何参数，以(x,y)的格式返回Turtle的当前位置，其中x和y代表2D矢量。默认值是（0.0, 0.0）。 下面是上述方法的实现和一些例子。 例子1 : # import turtle package import turtle # print the default # position i.e; (0.0, 0.0) print(turtle.pos()) # forward turtle by 150 pixels turtle.forward(150) # print current position # i.e; (150.0, 0.0) print(turtle.pos()) # forward turtle by 150 pixels # after taking turn right # by 90 degrees turtle.right(90) turtle.forward(150) # print position (after next move) # i.e; (150.0, -150.0) print(turtle.pos())输出:
示例 2: # import turtle package import turtle # print position (by default) # i.e; (0.0, 0.0) print(turtle.pos()) # turtle move forward # by 40 pixels turtle.forward(40) # print position (after move) # i.e; (150.0, 0.0) print(turtle.position()) # turtle move forward by 40 pixels # after taking right turn # by 45 degrees turtle.right(45) turtle.forward(40) # print position # (after next move) print(turtle.pos()) # turtle move forward by 80 # pixels after taking left # turn by 90 degrees turtle.left(90) turtle.forward(80) # print position # (after next move) print(turtle.pos()) # turtle move forward # by 40 pixels after taking # right turn by 90 degrees turtle.right(90) turtle.forward(40) # print position (after next move) print(turtle.position()) # turtle move forward by # 40 pixels after taking # left turn by 45 degrees turtle.left(45) turtle.forward(40) # print position # (after final move) print(turtle.pos())输出 :
