A list comprehension is an expression that produces a list, e.g.
[ i**2 for i in range(10) ]
Your example below uses a slice assignment.

You can use d.update(...)
It accepts both another dict as well as a generator expression that
produces item tuples, e.g.
d.update( (i, i**2) for i in range(10) )
Does that help?
