primes = []

for i in range(2, n + 1):
	for j in range(2, int(i ** 0.5) + 1):
 		if i%j == 0:
 			break
	else:
		primes.append(i)

print(primes)

Example 2: display prime numbers between two intervals in python

lowernum = int(input(“Enter your lower number”))
uppernum = int(input(“Enter your upper number”))
for num in range(lowernum,uppernum +1):
  if num> 1:
     for num in range(2,num):
        if (num % 1) == 0:
                    break
