如何在python中定义0到1之间的小数范围?python中的Range()函数只返回int值.我的代码中有一些变量,其编号从0到1不等.我对如何将其放入代码感到困惑.谢谢
我会在我的问题中添加更多内容.没有步骤或任何增量值会生成小数值.我必须使用一个变量,该变量的值可以是0到1.它可以是任何值.但程序应该知道它的范围从0到1的边界.我希望我清楚自己.谢谢
我有一个产生错误的python程序:

columns = range(len(phonlist[0]))

我在下面发布了我的部分代码.Newton()函数调用Bezier()函数.Bezier()函数有一个列表,从中我得到p0和p3.我想要做的是,在第一次迭代中,程序应该将plist中的第一项和第二项作为p0和p3.然后在第二次迭代中,p0和p3是第二和第三项,依此类推.每次迭代时,p0和p3值都应该改变.这就像新的p0是旧的p3.我无法正确地将其放入代码中.谢谢.
