Random list of numbers and add them

I am trying to create a program that asks user for a number and then generates a list of random numbers entered by the user and then uses a function to add these numbers together and return it back to the main function. I am so lost can someone please help me?

import random

def main():
    rand = int(input('How many random intergers? (Max 20)'))
    if rand <= 20:
        for x in range(rand):
            print (random.randint(1,9), end=' ')
        total = randnums(x)
        print('Integers total is ', total)
    else:
        print('Bad inpit. Maximum input is 20.')

Trying to get this sample output

How many random integers (max 20)? 12

5 9 7 7 9 8 8 2 5 5 8 7

Integers total is 80

To sample i integers without replacement from a pool of integers from 1 to n, and then sum them:

$ n=12345
$ i=100
$ seq ${n} | shuf -n ${i} | awk '{s+=$0}END{print s}'

To sample with replacement and sum:

$ seq ${n} | shuf -r -n ${i} | awk '{s+=$0}END{print s}'

You have at least to store your random outputs and only then you can add them...

E.G.

total = 0
for x in range(rand):
  rnum = random.randint(1,9)
  print (rnum, end=' ')
  total = total + rnum
print('Total: %s' %total)

import random
def f():
  n= input("give n : ")
  return sum([random.randint(0,10) for i in range(n)])

this will return the sum of 10 random number between 0 and 10

Import random

print (sum ([random.random () for x in range (1,input ("choose a list size"))]))
