Python 3

Question

It's been a week for me learning Python 3.
I'm trying to code a simple calculator.
I can't find the error in the code
The error message says that an error occurred when reading line 3.
Thanks for helping

while True :
print('1) add\n2) subtract\n3) multiply\n 4) quit')
x = input('Operation of Choice : ')

if x == 1 :
a = input('num1 : ')
b = input('num2 : ')
c = a + b
print('Your answer is',c )

elif x == 2 :
a = input('num1 : ')
b = input('num2 : ')
c = a - b
print('Your answer is',c )

elif x == 3 :
a = input('num1 : ')
b = input('num2 : ')
c = a * b
print('Your answer is',c )

elif x == 4 :
break

Answer 1

it's probably the first print statement .
u have to close the ( )

Answer 2

The error is in line 3. Changing anything in line 2 didn't made any difference. Thanks for helping tho
