Convert a nested for loop that increments the integer value of dictionary pair into a list comprehension

Anyway to turn the for loop and its nested for loop into one list comprehension? I did not find this particular type of conversion anywhere.

from collections import defaultdict
frequency = defaultdict(int)
for text in texts:
for token in text:
frequency[token] +=1

You can use collections.Counter:

collections.Counter

from collections import Counter
frequency = dict(Counter(token for text in texts for token in text))
