import randomrandom_integers = [random.randint(1, 100) for i in range(6)]print(random_integers)使用列表推导式创建随机浮点数列表还可以使用列表推导式和 random() 来生成浮点数列表。import randomrandom_floats = [random.random() for i in range(6)]print(random_floats)# 输出:[0.7740305693567944,...

用法是: numpy.random.random_integers(low,high=None,size=None) 生成闭区间[low,high]上离散均匀分布的整数值;若high=None,则取值区间变为[1,low] 用法及实现 high=None的情形 1 2 3 4 >>> np.random.random_integers(1, 6, 10) array([4, 5, 2, 3, 4, 2, 5, 4, 5, 4]) >>> ...
np.random.random_integers(low, high=None, size=None) 相比于randint它是在闭区间[low,high]或者[1, low]之间生成随机向量, 一般情况下更推荐使用np.random.randint替代. >>> np.random.random_integers(0, 1, size=(1,1)) <stdin>:1: DeprecationWarning: This function is deprecated. Please call ran...

To choose a sample from a range of integers, use range() for the population argument. This is especially fast and space efficient for sampling from a large population: sample(range(10000000), 60) """ 翻译:从总序列或集合中选择k个唯一或随机元素,返回一个新的列表包含从总列表来的元素,原始的...

random.randint(1,100)随机数中是包括1和100的。python中对random.randint() 的源码解释如下 def randint(self, a, b):"Return random integer in range [a, b], including both end points."翻译过来就是返回值是在 [a, b] 区间的随机数(integer类型),其中包括 a和 b。
