Python random number generator using generators

Python: Generators Yield Exercise-2 with Solution

Write a Python program to implement a generator that generates random numbers within a given range.

Sample Solution:

Python Code:

import random

def random_number_generator(start, end):
    while True:
        yield random.randint(start, end)

# Accept input from the user
start = int(input("Input the start value: "))
end = int(input("Input the end value: "))

# Create the generator object
random_numbers = random_number_generator(start, end)

# Generate and print 10 random numbers
print("Random numbers between",start,"and",end)
for _ in range(10):
    print(next(random_numbers))

Sample Output:

Input the start value: 1
Input the end value: 10
Random numbers between 1 and 10
10
6
4
6
6
5
6
2
8
9
Input the start value: 445
Input the end value: 760
Random numbers between 445 and 760
489
687
611
695
731
455
504
567
704
468

Explanation:

In the above exercise,

  • At first the code imports the random module, which provides functions for generating random numbers.
  • The "random_number_generator(start, end)" function is defined as a generator. It uses a while loop to continuously generate random numbers within the given range. It uses the yield keyword to generate random numbers.
  • The program prompts the user to input the start and end values for the random numbers range.
  • The generator object random_numbers is created by calling the random_number_generator function with the start and end values.
  • The program then iterates over the generator using a for loop. Here, it generates and prints 10 random numbers by calling next(random_numbers).
