唯一化以及其他的集合逻辑np.unique找出数组中的唯一值并返回已排序的结果np.in1d用于测试一个数组的值在另一个数组的情况。说到python，很多人熟悉又陌生，想学但是又不知道该从哪下手，今天我就来给大家聊聊python课程，职场人和大学生尤其注意了，增加竞争力的干货知识点来了！觉得python学习难，是因为没有反复练习，一般都是

function_name(list_name[:]),[:]相当于复制。 8.5传递任意数量的实参(可变参数) 有时候,你预先不知道函数需要接受多少个实参,好在Python允许函数从调用语句中收集任意数量的实参。 def make_pizza(*toppings): 形参名*toppings 中的星号让Python创建一个名为toppings 的空元组,并将收到的所有值都封装到这个元组...
So, the object's id is unique only for the lifetime of the object. After the object is destroyed, or before it is created, something else can have the same id. But why did the is operator evaluate to False? Let's see with this snippet. class WTF(object): def __init__(self): ...
