随机的

介绍

Random provides access to Python’s random module, which is available by default in VEXcode 123. 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.

以下是可用方法列表：

• 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.

• random – Returns a random float between 0.0 (inclusive) and 1.0 (exclusive).

• getrandbits – Returns an integer with a specified number of random bits.

• choice – Returns a random element from a non-empty list or sequence.

随机变量

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

Usage:
random.randint(a, b)

范围	描述
a	表示范围下限的整数。
b	表示范围上限的整数。

# Generate a random integer between 
# 1 and 10 (inclusive)
console.print(random.randint(1, 10))

制服

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

Usage:
random.uniform(start, end)

范围	描述
start	表示范围下限的浮点数或整数。
end	表示范围上限的浮点数或整数。

# Generate a random float between 1 and 10
console.print(random.uniform(1, 10), precision=4)

随机范围

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

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

范围	描述
start	可选。表示范围起始值的整数。默认值为 0。
stop	表示范围的最后一个值（不包括最后一个值）的整数。
step	可选参数。一个整数，表示范围内每个数字之间的差值。默认值为 1。

# Generate a random integer from 0 to 9
console.print(random.randrange(10))

# Generate a random integer from 5 to 14
console.print(random.randrange(5, 15))

# Generate a random integer from 10 to 50, stepping
# by 5
console.print(random.randrange(10, 50, 5))

随机的

random returns a random float between 0.0 (inclusive) and 1.0 (exclusive).

Usage:
random.random()

范围	描述
	此方法没有参数。

# Generate a random float between 0.0 and 1.0
console.print(random.random(), precision=1)

获取随机位

getrandbits returns an integer with a specified number of random bits, where the number of bits is an integer between 0 and 32.

Usage:
random.getrandbits(n)

范围	描述
n	An integer representing the number of random bits (0 <= n <= 32).

# Generate a random integer with 8 random bits
# (integer between 0 and 255)
console.print(random.getrandbits(8))

选择

choice returns a random element from a non-empty list or sequence.

Usage:
random.choice(sequence)

范围	描述
sequence	从中随机选择一个元素的非空序列（列表、元组或其他可索引对象）。

# Choose a random number from a list
console.print(random.choice([10, 20, 30, 40, 50]))
