pyxen.random

Generate random numbers. Available globally via from pyxen import *.

random.seed(42)
value = random.random()       # float in [0, 1)
roll = random.randint(1, 6)   # int in [1, 6]
pick = random.choice(items)   # random element from sequence

Methods

MethodReturnsDescription
seed(n)NoneSet the random seed for reproducible results
random()floatRandom float in [0, 1)
randint(a, b)intRandom integer in [a, b] inclusive
choice(seq)elementRandom element from a sequence

seed(n)

random.seed(42)

Set the internal state of the random number generator. Using the same seed produces the same sequence of numbers every time.

This is useful for:

  • Reproducible procedural generation
  • Deterministic game behavior for debugging
  • Consistent level layouts across runs

random()

value = random.random()

Returns a random float between 0 (inclusive) and 1 (exclusive).

Example — random velocity in any direction:

vx = (random.random() * 2.0) - 1.0   # range [-1, 1)
vy = (random.random() * 2.0) - 1.0

randint(a, b)

roll = random.randint(1, 6)

Returns a random integer N such that a <= N <= b. Both endpoints are included.

Example — 50% chance:

if random.randint(0, 1) == 1:
    spawn_coin()

Example — random tile variant:

random.seed(42)
for col in range(COLS):
    alt = random.randint(0, 99) <= 10   # 10% chance
    tile = (1 if alt else 0, 4)

choice(seq)

color = random.choice(["red", "green", "blue"])

Returns a random element from a non-empty sequence (list, tuple, or string).

Raises IndexError if the sequence is empty.

Example — random spawn position:

spawns = [(10, 20), (50, 80), (120, 40)]
x, y = random.choice(spawns)
