Hi folks,
import io
with io.open(filename, ‘r’) as fd:
lines = fd.readlines(hint=1000)
for line in lines:
# do something
I was just looking at the io module. io.open(‘file’, ‘r') returns an
io.TextIOWrapper object, which has the io.TextIOWrapper.readlines(hint=-1/)
method.

This is a variation on a data-compression technique called
RLE=Run-Length Encoding (excepting that in this case there is no need to
count the repetitions).

Dear Python Community,
I am new to python. I sucessfully installed python 3.9 from python.org on my

Hello all,

something already proposed.
In a professional environment, we've came to a point in which most people use
