python随機數生成小結

python随機數生成小結
#生成0-1的随機數
randData = random.random()
#生成1-10的整數
randData = random.randint(1,11)
#生成0-10的随機偶數
randData = random.randrange(0,11,2)
#seed函數生成一個随機因子，相同的随機因子生成的随機數一緻
random.seed(10)
randData = random.randint(1,11)
random.seed(10)
randData = random.randint(1,11)
#不同得随機因子生成得随機數不一緻
random.seed(10)
randData = random.randint(1,11)
random.seed(11)
randData = random.randint(1,11)
#生成一個1-5之間得浮點數
randData = random.uniform(1,5)
print(randData)

print(random.choice(strRand))
---輸出 w

#将資料打亂
