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
            else:
                print(num)
