python随机数生成小结
#生成0-1的随机数
randData = random.random()
#生成1-10的整数
randData = random.randint(1,11)
#生成0-10的随机偶数
randData = random.randrange(0,11,2)
#seed函数生成一个随机因子，相同的随机因子生成的随机数一致
random.seed(10)
randData = random.randint(1,11)
random.seed(10)
randData = random.randint(1,11)
#不同得随机因子生成得随机数不一致
random.seed(10)
randData = random.randint(1,11)
random.seed(11)
randData = random.randint(1,11)
#生成一个1-5之间得浮点数
randData = random.uniform(1,5)
print(randData)
           

#choice随机选择某个值
strRand = 'welcome to my world'
tupRand = ('welcome', 'to', 'my', 'world')
lstRand = ['welcome', 'to', 'my', 'world']
print(random.choice(strRand))
---输出 w
print(random.choice(tupRand))
---输出 to
print(random.choice(lstRand))
---输出 my
#将数据打乱
lstRand = ['welcome', 'to', 'my', 'world']
random.shuffle(lstRand)
print(lstRand)
输出 ['welcome', 'world', 'my', 'to']
#从指定序列在随机抽取定长序列,原始序列不变
strRand = 'welcome to my world'
tupRand = ('welcome', 'to', 'my', 'world')
lstRand = ['welcome', 'to', 'my', 'world']
print(random.sample(strRand,2))
输出 ['m', 'c']
print(random.sample(tupRand,2))
输出 ['world', 'to']
print(random.sample(lstRand,2)
输出 ['to', 'welcome']
