There should only be one input statement:
choice = int(raw_input())

The program now requires 4 inputs, which is not what you want.

Since you are starting, consider using 3.3 insteadd of Python 2 unless 
you have a very good reason.

if choice == 1:
etc.

Take out 'amounted'

Because it is waiting for 3 more inputs. See above. Now, you can shorten 
and improve the program after the one input statement.

data = (
     ('Pizza', 20.0, 0.15),
     ('Steak', 40.0, 0.20),
     ('Pasta', 14.0, 0.12),
     ('Burger', 23.0, 0.17),
     )

if 1 <= choice <= len(data):
     product, price, tax = data[choice]
     bill = "The bill for {} is {}, along with tax of {}, total {}"
     print(bill.format(product, price, tax, price + tax))
else:
     print('I do not know what you mean.')

print() is for 3.x, but works here for 2.x also.
