5)like:传入array_like(可选填,1.20.0新添加的功能) 简言之就是使用对象创建不属于NumPy的数组。如果array_like当做like传入的话,必须保证创建的数组对象要适用于刚刚通过like传入的参数。 听起来就头大,这里可以简单任务like要和array_like要匹配 返回值:ndarray 给定shape,dtype,order条件下的数组 3、简单代码 i...

runoob like ITuple(元组)元组(tuple)与列表类似,不同之处在于元组的元素不能修改。元组写在小括号 () 里,元素之间用逗号隔开。 元组中的元素类型也可以不相同: 实例 #!/usr/bin/python3 tuple = ( 'abcd', 786 , 2.23, 'runoob', 70.2 ) tinytuple = (123, 'runoob') print (tuple) # 输出...
