Generate a Random Integer

Swift

// Simulate casting a single, six-sided die and print the result
let firstDie = Int.random(in:1...6)
print(firstDie)

// Simulate casting two six-sided dice and print the sum
let firstDie = Int.random(in:1...6)
let secondDie = Int.random(in:1...6)
print(firstDie+secondDie)

Python

from random import randint
print(randint(1,6))

from random import randint
print(randint(1,6) + randint(1,6))

Common Lisp

; Seed the random state
(setf *random-state* (make-random-state t))

(defvar firstDie)
(setq firstDie (random 6))

(format t "~d~%"
	firstDie)

; Seed the random state
(setf *random-state* (make-random-state t))

(defvar firstDie)
(defvar secondDie)
(defvar dieResults)

(setq firstDie (random 6))
(setq secondDie (random 6))
(setq dieResults firstDie + secondDie)

(format t "~d~%"
	dieResults)
