Python Random Boolean


Topics Covered

Python provides several ways to generate Random Boolean values. One of the easiest ways is to use the random module, which is included in the standard library. This module provides various functions that allows you to generate random numbers and values, including Boolean values.

Generate Random Boolean (True and False)

To produce a Random Boolean value in Python, you can use the random.choice() function from the random module. This function takes a sequence as an argument and returns a randomly selected item, from that sequence. To generate a random Boolean value, you can pass a sequence containing the values True and False to the random.choice() function.

Example

import random
bool_value = random.choice([True, False])
print(bool_value)

In an above example, the random.choice() function randomly selects either True or False from the sequence [True, False] and assigns the result to the variable bool_value. The print() function is then used to display the value of bool_value.

Python – Generate Random Numbers Between 0 and 1

In Python, we can produce random numbers between 0 and 1 using the random module, which is included in the standard library. The random module provides several functions that allow us to generate random numbers and values.

In order to generate a random number between 0 and 1 in Python. We can use the random.random() function, from the random module. This function gives back a random decimal number between 0 and 1.

Example

import random
random_number = random.random()

print(random_number)

In an above example, the random.random() function produces a random floating-point number between the 0 & 1 and assigns it to the variable, namely random_number. Then the print() function is used to display the value of random_number.

Python – Generate Random Numbers Between two Specified Values

To generate a random numbers between the two specified values, we can use the uniform() function from the random module. In an example below, we will generate a random number between 0 and 10. So here we will use the uniform() function, with arguments 0 and 10.

Example

import random
random_number = random.uniform(0, 10)

print(random_number)

In an above example, the random.uniform() function generates a random numbers between 0 and 10 (including floating numbers). And assigns it to the variable random_number. The print() function is then used to display the value of random_number.

Python – Generate Random Numbers Between two Specified Values Without Decimals

In Python, we can generate random numbers without decimals using the random module. The random module provides several functions that allow you to generate random numbers and values.

To generate a random integer between two specified values, we can use the randint() function from the random module. This function takes two arguments: the lowest and highest values of the range. It returns a random integer between these two values, including both endpoints.

Example

import random
random_number = random.randint(0, 100)

print(random_number)

In an above example, the random.randint() function generates a random integer between 0 and 100, including both endpoints, and assigns it to the variable random_number. The print() function is then used to display the value of random_number.

Python Random Boolean With Probability

In Python, we can generate a random boolean value with a specific probability using the random module. The random module provides several functions that allow you to generate random numbers and values.

To generate a random boolean value with a specific probability, we can use the random.random() function from the random module to generate a random floating-point number between 0 and 1. You can then use this value to determine the boolean value with the desired probability.

Example

import random
probability = 0.7  # probability of generating True
random_number = random.random()

if random_number < probability:
    random_boolean = True
else:
    random_boolean = False

print(random_boolean)

In an above example, we first set the probability of generating True to be 0.7 (or 70%). We then use the random.random() function to generate a random floating-point number between 0 and 1 and assign it to the variable random_number. We then use an if statement to determine the boolean value with the desired probability. If the value of random_number is less than the probability value, we set the value of random_boolean to True, otherwise we set it to False. Finally, we use the print() function to display the value of random_boolean.

Alternatively, we can use the random.choices() function to randomly select from a list of values with specified probabilities. You can create a list of two values (True and False) with their respective probabilities and use the random.choices() function to randomly select one value from the list.

Here is an Example

import random
probability = [0.7, 0.3]  # probability of generating True and False
options = [True, False]
random_boolean = random.choices(options, probability)[0]

print(random_boolean)

In this example, we first create a list of two values [True, False] and a corresponding list of probabilities [0.7, 0.3]. We then use the random.choices() function to randomly select one value from the list with the specified probabilities. Finally, we use the print() function to display the value of random_boolean.

These methods can be useful in a variety of applications, such as simulation, testing, and data generation. By generating random boolean values with specific probabilities, you can simulate the behavior of a wide range of systems and processes, and generate random data for testing and validation purposes.

Using Random Boolean Values in Python

Random Boolean values are often used in programming to simulate the behavior of switches, flags, and other logical values. For example, you can use Random Boolean values to simulate the behavior of a traffic light or a switch that turns on and off randomly. You can also use Random Boolean values to generate random data for testing and validation purposes.

Here’s is how random Boolean values can be used in a program.

Example

import random
# Simulate the behavior of a traffic light
while True:
    red_light = bool(random.randint(0, 1))
    yellow_light = bool(random.randint(0, 1))
    green_light = bool(random.randint(0, 1))

    if red_light:
        print("Stop")
    elif yellow_light:
        print("Slow down")
    elif green_light:
        print("Go")

In an above example, the while loop generates Random Boolean values for the red_light, yellow_light, and green_light variables to simulate the behavior of a traffic light. Depending on the values of these variables, the program. Copy the code and run it in your Python compiler and see how it works.
