Generating random number listing in Python

There is a need to generate random numbers when studying a model or beliefs of a program for different range of values. Python tin can generate such random numbers by using the random module. In the below examples nosotros will beginning run into how to generate a single random number then extend it to generate a list of random numbers.

Generating a Unmarried Random Number

The random() method in random module generates a float number between 0 and 1.

Instance

import random due north = random.random() print(north)

Output

Running the above lawmaking gives us the following consequence −

0.2112200

Generating Number in a Range

The randint() method generates a integer between a given range of numbers.

Example

import random northward = random.randint(0,22) impress(n)

Output

Running the higher up code gives the states the following result −

ii

Generating a List of numbers Using For Loop

We can apply the to a higher place randint() method forth with a for loop to generate a list of numbers. We showtime create an empty listing and then suspend the random numbers generated to the empty list i by ane.

Case

import random randomlist = [] for i in range(0,5): n = random.randint(1,30) randomlist.append(northward) print(randomlist)

Output

Running the to a higher place code gives us the post-obit outcome −

[10, 5, 21, i, 17]

Using random.sample()

We can besides employ the sample() method available in random module to direct generate a listing of random numbers.Here nosotros specify a range and give how many random numbers we need to generate.

Case

import random #Generate 5 random numbers betwixt 10 and xxx randomlist = random.sample(range(10, 30), 5) print(randomlist)

Output

Running the above lawmaking gives us the following result −

[16, nineteen, 13, eighteen, 15]
