生成属于[0, 9]的随机数

• aneuryzm asked:

  • 怎么在Python中生成0到9（包括0与9）的随机整数
  • 例如 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

• Answers:

  • kovshenin – vote: 2344

  • 试试：

  • from random import randrange
    print(randrange(10))

  • 文档： https://docs.python.org/3/library/random.html#random.randrange

  • JMSamudio – vote: 637

  • import random
    print(random.randint(0,9))

  • random.randint(a, b)

  • 随机返回整数N, N∈[a, b]

  • 文档: https://docs.python.org/3.1/library/random.html#random.randint

  • Andrew Hare – vote: 159

  • 试试这个

  • from random import randrange, uniform
    
    # randrange gives you an integral value
    irand = randrange(0, 10)
    
    # uniform gives you a floating-point value
    frand = uniform(0, 10)

Generate random integers between 0 and 9

• aneuryzm asked:

  • How can I generate random integers between 0 and 9 (inclusive) in Python?
