Return the size of a python query in bytes

I have the following pymongo code: 

import pymongo
import time
start_time = time.time()

connection_string = 'mongodb://localhost'
connection = pymongo.MongoClient(connection_string)
database = conn
pipe = [ 
  *some code here*
  ]
start_time = time.time()
query = list(database.solution3.aggregate(pipe,allowDiskUse=True))
print("--- %s seconds ---" % (time.time() - start_time))

How can i know the size of this query after it's executed??

If you check the length of the string representation of your query list you will get the number of bytes in the list.

Just try:

print(f'Length/size of query is --> {len(str(query))}')

You can verify by writing it to disk and checking the size in your file viewer (of course writing a string representation of a list and the length of a string representation of a list should be the same).

Something as simple as:

with open('<path to and file name>', 'w') as f:
    f.write(str(query))
