Question

Could you solve the question below with python code?

suppose there are two groups of in a lottery system. A player should pick five numbers from first fifty positive integer numbers. And a second player should picks 1 number from the first 10 positive integer numbers. If a player chose 7, 20, 21, 22, 40 for the first group and 3 for the second group. Please write a function named chose that randomly creates and returns six numbers.

First 5 values shouldn't be repeated. For example, output will be this:

chose()

array([21, 5, 29, 22, 4, 1])

Answer 1

The code is written in python3.

The following code of the program is explained with comments. Please let me know if you have any doubts regarding the code.

Code:

import array

import random

# This function returns an array where first five numbers are between 1 and 50 and the last number is between 1 to 10

def chose():

    # Creating an object of type array where the type of elements is unsigned int with no elements at start

    arr = array.array('i',[])

    # Creating a list of numbers of first 50 natural numbers

    values = [i+1 for i in range(50)]

    # This loop is iterated when the first five random numbers are appened to the array

    while len(arr) < 5:

        # Generating an random value from the values list

        random_value = random.choice(values)

        # If the random_value is not in the arr

        if random_value not in arr:

            # Append it to arr

            arr.append(random_value)

    # Appending an random value from the first 10 natural numbers to the arr

    arr.append(random.choice(values[:10]))

    # Returning the arr

    return arr

# This is the main function

def main():

    # Storing the result of the chose() function

    res = chose()

    # Printing the result of the chose() function

    print(res)

# Calling the main function

main()
