import random

# 1. 获取范围内的随机整数
v = random.randint(10, 20)
print(v)

# 2. 获取范围内的随机小数
v = random.uniform(1, 10)
print(v)

# 3. 随机抽取一个元素
v = random.choice([11, 22, 33, 44, 55])
print(v)

# 4. 随机抽取多个元素
v = random.sample([11, 22, 33, 44, 55], 3)
print(v)

# 5. 打乱顺序
data = [1, 2, 3, 4, 5, 6, 7, 8, 9]
random.shuffle(data)
print(data)
