typeerror - Why do I keep getting: 'int' object is not callable in Python? -

x = 4 y = 5 = 3(x + y) print(a) 

---

i keep trying solve that. i've tried this.

---

x = input("enter value x:") 

enter value x:4

y = input("enter value y:") 

enter value y:5

a = 3 x + y 

---

what doing wrong?

i suspect want 3(x + y) acted upon in algebra, multiply result of x + y 3. need use multiplication operator *:

a = 3 * (x + y) 

python take parentheses after token function call per f(x + y), , since 3 not function, told not "callable" (meaning function, or can treat function).
