get value using max(dict comprehension)

I'm storing values in a dict in this way: 

def fname():
    return max({(x): x**2 for x in range(1, 20)})

The problem is this returns the value of max key, and i need the value of that key.

How the get the value or rewrite this so that i do get the value of the max key? Preferably without the use of itertools.

EDIT: I forgot to mention, i would need this written in a single line.

As it is requested to print the value of largest key, we have to find the largest key.

l = sorted(list({x:x**2 for x in range(1, 20)}.items()), key = lambda v:v[0], reverse=True)[0][1]
print(l)
# 361

In the above example, largest value is also having largest key. Hence let's solve by different example

d = {1:4,2:3}
l = sorted(list(d.items()), key = lambda v:v[0], reverse=True)[0][1]
print(l)
# 3

Note it prints 3 and not 4.

you can get a list of the values in the dict 

max({(x): x**2 for x in range(1, 20)}.values())
361
