Undefined variable in dict comprehension

[Yanpas]

Example

import sys
from collections import defaultdict

def xx():
    dmap = defaultdict(list)
    sizes = {db:int(sz)//(1 << 20) for sz, db in [ln.split() for ln in open(sys.argv[1]).readlines()]}
    return {srv:sum([sizes[d] for d in dbs]) for srv,dbs in dmap.items()}

Undefined variable: 'dbs'

"python.analysis.downloadChannel": "beta"

Closing as a duplicate for now.
