Creating random list of number in python within certain range

Question

I want to create 10,000 random numbers withing the range of 1 to 100.

How can I do with python?

I can use for loop and with each for loop I can use random.sample() or random.random() function.

Is there any other way, without using any for loop I can generate it with built-in function ?

[rand.randrange(1,100) for _ in range(10000)] should do. But maybe you've got demands for no-repeats, etc... we don't know — Jean-François Fabre

What is wrong with using random.sample(range(1,100), 10000) exactly? (for sampling without replacement or random.choices() with replacement) — Chris_Rands

Now, when you say "I can use random.sample or random.random() function.", do you mean "I know I can use sample() or random(), but I am receptive to using other functions from the random module", or do you mean "for this assignment, I am allowed to use only sample() and random(), and all other functions are off limits, which is why I'm not using randint()"? — Kevin

@Chris_Rands with random.sample(range(1,100), 10000) you will get error ValueError: Sample larger than population or is negative — Adelina

@Jean-FrançoisFabre I can use for loop but i want to avoid it — Mahek Shah

For python 3.6:

import random

my_randoms = random.choices(range(1,100), k=10000)
print(my_randoms)

For older would still need to use loops:

my_randoms = [random.randrange(100) for x in range(10000)]

thanks. Its working perfectly in python 3. I can use it. Do you know anything similar in python 2. As I go through python 2 documentation. I didn't found any.

can you specify the min version of python to use this? it is at least 3.5 or 3.6
