Python Program to Generate Random Numbers from 1 to 20 and Append Them to the List

When it is required to generate random numbers within a given range and append them to a list, a method is defined, that generates random numbers and ‘append’s them to an empty list.

Below is the demonstration of the same −

Example

 Live Demo

import random def random_gen(beg, end, my_num):    my_result = []    for j in range(my_num):       my_result.append(random.randint(beg, end))    return my_result my_num = 19 beg = 1 end = 20 print("The number is :") print(my_num) print("The start and end values are :") print(beg, end) print("The elements are : ") print(random_gen(beg, end, my_num))

Output

The number is : 19 The start and end values are : 1 20 The elements are : [12, 12, 5, 12, 11, 1, 5, 12, 19, 19, 7, 15, 18, 18, 10, 14, 3, 2, 11]

Explanation

• A method named ‘random_gen’ is defined, that takes three parameters- the beginning, end and a number.

• The method generates random numbers with the range of ‘beginning’ and ‘end’.

• It appends it to a list.

• Outside the method, three values are defined.

• They are displayed on the console.

• The method is called by passing this values as parameters.

• The output is displayed on the console.
