The problem is that you are somehow executing the Python
interpreter prompt in the interpreter. WE need to know exactly how you
are running the code.
Its possible you are trying to execute the shell window of IDLE (or some
other IDE) or that you are copy/pasting too much code from one window to
another. But its impossible to guess.
You need to tell us *exactly* how you run your code.
What tools are you using? What buttons/menus you use etc.

So far so good. That looks like you are typing into the
interactive mode of the Python interpreter. Now if you
just hit Return you should see "correct" being printed
on the screen.

But this looks like an OS terminal of some kind trying
to execute a file called test.py
But that file does not contain the Python code above,
it includes the header printed by the interpreter in
interactive mode. That is not executable code and so
Python complains.
test.py should only contain:
a=2
if a==2 :
print("correct")
and nothing else.
