how to get prime numbers in a range in python code example

Example 1: list of prime numbers in python

n = 20
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: prime numbers upto n in python

lower = int(input("Enter lower range: "))  
upper = int(input("Enter upper range: "))  
  
for num in range(lower,upper + 1):  
   if num > 1:  
       for i in range(2,num):  
           if (num % i) == 0:  
               break  
       else:  
           print(num)
