Print 20 prime numbers in a row

Question

My project is to print prime numbers between 0 and 1000, but also display 20 of the prime numbers per row. But i was unable to print the numbers on new rows.Could anyone help me with it.Thanks in advance

My code is:
lower = 1

upper = 1000

print("The prime numbers between", lower, "and", upper, "are:")

for num in range(lower + 1, upper + 1):

if (num % 2) != 0 and (num % 3) != 0:

print(num)

elif num//2 == 1:

print(num)

Answer 1

here is my try, printing in rows is done with a for loop:

Answer 2

also, i think the logic is wrong. this way you are detecting not multiples of 2 and 3 only. A highly inefficient algorithm to check wether p is prime is to check if p is a multiple of some number less than p, if it is not, p is prime.

Answer 3

Try this

n = int(input())
for i in range(1,n+1):
if(i>1):
for j in range(2,i):
if(i%j==0):
break
else:
print(i,end=' ')

Answer 4

print(num, end=' ')
