Generating Random Integers When you need random integers, you can use therandom.randint()function. random.randint() Therandom.randint()function returns random integers from the specified range. You can specify the range by providing thelowandhighvalues as arguments. Optionally, you can also specify...

常常有这样的情况,我们希望 NumPy 初始化数组的值。 NumPy 提供了ones()和zeros()之类的函数,以及用于随机数生成的random.Generator类来实现。 你需要做的就是传入你想要生成的元素数量: >>> np.ones(3)array([1., 1., 1.])>>> np.zeros(3)array([0., 0., 0.])>>> rng = np.random.default_...
