Aleatorio

Introducción

Random provides access to Python’s urandom module, which is available by default in VEXcode IQ (2nd gen). These methods let you generate random numbers, floats, and values from lists or ranges—useful for adding unpredictability to games, behaviors, and autonomous decision-making.

A continuación se muestra una lista de los métodos disponibles:

• randint – Returns a random integer between two values (inclusive).

• uniform – Returns a random float between two values.

• randrange – Returns a random integer from a range with an optional step.

Generadores de números

randint

randint returns a random integer between two values (inclusive), where both values are integers.

Usage:
urandom.randint(a, b)

Parámetro	Descripción
a	Un número entero que representa el límite inferior inclusivo del rango.
b	Un número entero que representa el límite superior inclusivo del rango.

# Generate a random integer between
# 1 and 10 (inclusive)
urandom_int = urandom.randint(1, 10)
brain.screen.print(urandom_int)

# urandom_int = (random integer between 1 and 10)

uniform

uniform returns a random float between two values, where both values are floats or integers.

Usage:
urandom.uniform(start, end)

Parámetro	Descripción
start	Un flotante o entero que representa el límite inferior del rango.
end	Un número flotante o entero que representa el límite superior del rango.

# Generate a random float 
# between 5.0 and 10.0
urandom_uniform = urandom.uniform(5.0, 10.0)
brain.screen.print(urandom_uniform)

# urandom_uniform = (random float 
# between 5.0 and 10.0)

randrange

randrange returns a random integer from a range with an optional step, where both the start and stop values are integers.

Usage:
urandom.randrange(start, stop, step)

Parámetro	Descripción
start	Opcional. Un entero que representa el valor inicial inclusivo del rango. El valor predeterminado es 0.
stop	Un número entero que representa el valor final exclusivo del rango.
step	Opcional. Un entero que representa la diferencia entre cada número del rango. El valor predeterminado es 1.

# Generate a random integer from
# 0 to 9 (exclusive of 10)
urandom_range = urandom.randrange(10)
brain.screen.print(urandom_range)

# urandom_range = (random integer from 0 to 9)

# Generate a random integer from
# 5 to 15 (exclusive of 15)
urandom_range = urandom.randrange(5, 15)
brain.screen.print(urandom_range)

# urandom_range = (random integer from 5 to 14)

# Generate a random integer from
# 10 to 50, stepping by 5
urandom_range = urandom.randrange(10, 50, 5)
brain.screen.print(urandom_range)

# urandom_range = (random multiple of 5 between 10 and 45)
