Question

Write a python function genRandomVect that returns a random 1d numpy array of size (50,) where each element is an integer sampled from [0, 100) and no two elements in the vector are the same.
Your code snippet should define the following variable:

Name Type Description
genRando function function that returns a numpy array of shape (50,) that
contains random elements on the interval [0, 100) and
no duplicates

Answer 1

Answer:

import numpy as np

def genRandomVect():

   arr = np.random.choice(range(100),size=(50,),replace=False)

   return arr

 

print("Random 1D numpy array where each element is an integer sampled from: [0, 100) ")

print( genRandomVect() )

Explanation:

• Create a function to create a numpy array with random integers in range[0,100) with no duplicates
• Use the random.choice to select random values from range[0,100)  and size attribute to take the size of the required array .
• Finally return the numpy array.
