TypeError in function argument.

Question

I typed program as

def print_sum_twice(x,y):
print(x+y)
print(2(x+y))
print_sum_twice(5,8)
13
Traceback (most recent call last):
File "<pyshell#42>", line 1, in <module>
print_sum_twice(5,8)
File "<pyshell#41>", line 3, in print_sum_twice
print(2(x+y))
TypeError: 'int' object is not callable

Print (2*(x+y))
