Fastest Way of Writing/Reading Data

[Larz60+]

you can use a flat file for storage, open using mode 'w+', ('a+' if you wish to keep old contents) and after each write make a call to flush()

example -- something like this (won't run as written, but syntax is there):

import os
from pathlib import Path

# following assures starting directory same as script.
os.chdir(os.path.abspath(os.path.dirname(__file__)))

# create ref to script directory
homepath = Path('.')

# Here, create a subdirectory to hold output data (move this to wherever you wish)
# if paths exists, do nothing. If not create them
OutDatapath = homepath / 'data_out'
OutDatapath.mkdir(exist_ok=True)

outfile = OutDatapath / 'MyData.txt' # Rename this as you wish

with outfile.open('w+') as fp:
    # ... your code here
    fp.write(scraped_data)
    fp.flush()

since the file is flushed each time written, it can be opened for read by another program, and get all data up to the last write.
