随机数生成器 - 停止

Question

I am using Python.

How can I make a code that generates random numbers between 1 and 1000 (inclusive) infinitely until it generates the number 39 and stops?

Here is what I've tried so far, however it has not worked:

import random

print(random.randint(1,1000))

if random.randint=39:

break

Answer 1

Try this code:

import random
while random.randint(1,1000) != 39:
    pass

Or (depending on your needs):

import random
while True:
    if random.randint(1,1000) == 39:
        break

If you want to create generator try something like this :

import random

def generate_numbers(exact_number):    
    while True:
        n = random.randint(1,1000)
        if n == exact_number:
            break
        yield n

#example usage
for i in generate_numbers(39):
    print(i)
