random函数用法python

1本文需要加载的模块是：random

2给出0到10之间的随机整数：import randoma = random.randint(0,10)print(a)

3给出9到10之间的随机实数：import randoma = random.uniform(9,10)print(a)

4从9、19、29、39、……、99之间，随机选取一个实数：import randoma = random.randrange(9, 100, 10)print(a)

5从列表[5,6,7,8,9]里面，随机选取一个数：import randoma = random.choice([5,6,7,8,9])print(a)

6从一个字符串里面，随机选取一个字符：import randoma = random.choice("从一个字符串里面，随机选取一个字符！")print(a)

7随机打乱列表里面的字符顺序：import randoma = ["p","q","r","s","t","p","q","r","s","t","p","q","r","s","t",]random.shuffle(a)print(a)

8从列表里面随机选取9个数字：import randoma = range(3,100,2)b = random.sample(a, 9)print(b)
