How do I generate multiple DIFFERENT random numbers in python?-CodePudding

I'm trying to create a code that produces a list of 5 different random number. Here is my current code:

import random

rN0 = random.randint(1, 50)
rN1 = random.randint(1, 50)
rN2 = random.randint(1, 50)
rN3 = random.randint(1, 50)
rN4 = random.randint(1, 50)

randomNumber = [rN0, rN1, rN2, rN3, rN4]

But, sometimes it produces two or more of the same number in the list. I would like each number in the list to be unique every time. Help please?

Try:

import random

def newNum(nums):
    while True:
        n = random.randint(1, 50)
        if n in nums:
            continue
        return n

randomNumber = []
for _ in range(5):
    n = newNum(randomNumber)
    randomNumber.append(n)

print(randomNumber)

Or:

import random

randomNumber = random.choices(range(1, 51), k=5)
print(randomNumber)

You can use random.sample that picks n random numbers from a given range:

>>> random.sample(range(1, 50), 5)
[4, 41, 16, 40, 25]
