random_integers(low[, high, size]) 返回随机的整数,位于闭区间 [low, high]。 Notes To sample from N evenly spaced floating-point numbers between a and b, use: a + (b - a) * (np.random.random_integers(N) - 1) / (N - 1.) Examples >>> np.random.random_integers(5) 4 >>> t...
>>> rg = np.random.default_rng(1) # create instance of default random number generator >>> a = np.ones((2, 3), dtype=int) >>> b = rg.random((2, 3)) >>> a *= 3 >>> a array([[3, 3, 3], [3, 3, 3]]) >>> b += a >>> b array([[3.51182162, 3.9504637 , ...
[4, 5]]) Choose five random numbers from the set of five evenly-spaced numbers between 0 and 2.5, inclusive (i.e., from the set ): >>> 2.5 * (np.random.random_integers(5, size=(5,)) - 1) / 4. array([ 0.625, 1.25 , 0.625, 0.625, 2.5 ]) Roll two six sided dice 1000 ...
BitGenerators: Objects that generate random numbers. These are typically unsigned integer words filled with sequences of either 32 or 64 random bits. Generators: Objects that transform sequences of random bits from a BitGenerator into sequences of numbers that follow a specific probability distributio...

Examples --- >>> np.random.randint(2, size=10) array([1, 0, 0, 0, 1, 1, 0, 0, 1, 0]) >>> np.random.randint(1, size=10) array([0, 0, 0, 0, 0, 0, 0, 0, 0, 0]) Generate a 2 x 4 array of ints between 0 and 4, inclusive: >>> np.random.randint(5, si...
NumPy's random module can also be used to generate an array of random numbers. For example, importnumpyasnp# generate 1D array of 5 random integers between 0 and 9integer_array = np.random.randint(0,10,5)print("1D Random Integer Array:\n",integer_array)# generate 1D array of 5 rando...
