single line if else in python dictionary comprehension method

I just tried a list comprehension like this

[i if i==0 else i+100 for i in range(0,3)]

and it worked, but when I tried a similar dict comprehension, it throws an error:

d={3:3}
{d[i]:0 if i==3 else d[i]:True for i in range(0,4) }

What could be the reason? How can I use dict comprehension using if else?

The error this produces:

    {d[i]:0 if i==3 else d[i]:True for i in range(0,4) }
                             ^
SyntaxError: invalid syntax

Note: The example I used here is just a random one, not my actual code. I can do this with alternative an solution, but I'm only looking at dict comprehensions now to learn.
