Problems python3 with multiplication sign

Question

I am in the first basic step of python and when I write this code:
print(-7)*(-4)
which as far as I understand would give the answer -28
I get this:
-7

Traceback (most recent call last):
File "./Playground/file0.py", line 1, in <module>
print(-7)*(-4)
TypeError: unsupported operand type(s) for *: 'NoneType' and 'int'

What rookie mistake am I making trying to use the symbol for multiplication?
I have tried both * at numbers and at the keyboard.

Answer 1

print((-7)*(-4))

I printed the above statement..and it did not gave any error..and ans is also correct i.e. 28

Answer 2

print((-7)*(-4))
Output:28
As negative number * negative number = positive number

Answer 3

Ok first try to know that print is a function in python 3 so it need parenthesis print() like this but in python 2 no parenthesis was required and if you are using IDE for python3 then you must write it like print((-7)*(-4)).

Answer 4

You're missing an enclosing parenthesis to bind what you want to print

Answer 5

negative*negative=positive
positiv*positive=positive
negative*positive=negative
positive*negative=negative
