It’s possible to generate a single number, an array of numbers, or a multidimensional array of numbers, all of which belong to a Poisson distribution: Python >>> import numpy as np >>> rng = np.random.default_rng() >>> scalar = rng.poisson(lam=5) >>> scalar 4 >>> sample_...
Write a NumPy program to sort the specified number of elements from beginning of a given array.Sample Solution: Python Code:# Importing the NumPy library import numpy as np # Creating an array of 10 random numbers nums = np.random.rand(10) # Displaying the original array print("Original ...
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...
