Tuples have many uses in Python programming. 一个特别重要的用例是当您希望从Python函数返回多个对象时。 One especially important use case is when you want to return more than one object from your Python function. 在这种情况下,您通常会将所有这些对象包装在一个元组对象中,然后返回该元组。 In that...

1、rand()、random产生随机的浮点数,但基本在0-1区间内,添加一个参数标注随机序列的size,这个函数的用法和random的一致,两者区别就是一个可以生成二维序列,一个不行。 numpy.random.rand(d0,d1,…,dn) rand函数根据给定维度生成[0,1)之间的数据,包含0,不包含1 ...
