Change delimiter on “for each” loops on Strings in python

Question

I need to read an input text file in python, by streaming line by line. That means load the text file line by line instead of all at once into memory. But my line delimiters

Answer 1

import re
def open_delimited(filename, delimiter, chunksize=1024, *args, **kwargs):
    with open(filename, *args, **kwargs) as infile:
        remainder = ''
        for chunk in iter(lambda: infile.read(chunksize), ''):
            pieces = re.split(delimiter, remainder+chunk)
            for piece in pieces[:-1]:
                yield piece
            remainder = pieces[-1]
        if remainder:
            yield remainder

for line in open_delimited("log.txt", delimiter='/'):
    print(repr(line))
