Python program to design a biased dice throw function

An example of random.choice() in Python: Here, we are going to learn how to design a function that can be used as biased dice throw and the function will return a random value?

Here, we are going to build a biaseddice() function using python. The program is so simple as an introductory program and similar to the function dice() for defining a function. The function is going to use an inbuilt library naming random(). This random python library helps us to choose a random value of the variable within the range or take some random value from a given set.

        random.choice([1,2,3,4,4,4,5,6,6,6])
    

The above function will choose a random value with probability of:

        DICE FACE = PROBABILITY OF OCCURRENCE
        -    1 = 0.1
        -    2 = 0.1
        -    3 = 0.1
        -    4 = 0.3
        -    5 = 0.1
        -    6 = 0.3
    

Each member of the set have equal probability to get fired when random.choice() function is called and if a member is present multiple times in the set, its probability increases as well.

Here is the code

import random

# function to return the randon value 
# on biased dice roll
def biaseddice():
    return random.choice([1,2,3,4,4,4,5,6,6,6])

# main code i.e. calling the function
print('DICE THREW : ', biaseddice())
print('DICE THREW : ', biaseddice())
print('DICE THREW : ', biaseddice())
print('DICE THREW : ', biaseddice())
print('DICE THREW : ', biaseddice())
print('DICE THREW : ', biaseddice())
print('DICE THREW : ', biaseddice())
print('DICE THREW : ', biaseddice())
print('DICE THREW : ', biaseddice())
print('DICE THREW : ', biaseddice())

Output

DICE THREW :  6
DICE THREW :  4
DICE THREW :  5
DICE THREW :  6
DICE THREW :  2
DICE THREW :  2
DICE THREW :  6
DICE THREW :  4
DICE THREW :  4
DICE THREW :  3
