What is the different

Question

I have 2 codes:
def is_prime(num):
for k in range(2,num):
if num % k ==0:
return False
return True
def prime_number(x):
for i in range(3,x):
if is_prime(i):
yield i
print(list(prime_number(1000000)))

and
def is_prime(num):
for k in range(2,num):
if num % k ==0:
return False
return True
def prime_number(x):
for i in range(3,x):
if is_prime(i):
yield i
for i in prime_number(1000000):
print(i)
