Produce a list named primes which only contains the central number of two twin primes in the range [2,1000]. (A twin prime is a prime number which has another prime number two away from it, like 41 and 43; in this case, we would add the number 42 to our list.) We provide a function is_prime to assist you with this. Call it like this: is_prime (5).

def is_prime (x):

for i in range (2, x):

if x%i==0:

return False

return True

primes=[]

for i in range (2,1001):

# print (i, is_prime (i), is_prime (i+2))

if is_prime (i) and is_prime (i+2):

primes. append (i+1)

print (primes)
