TypeError: a bytes-like object is required, not 'str' when splitting lines from .gz file

Question

I have a gz file sample.gz.

This is first line of sample gz file.
This is second line of sample gz file.

I read this .gz file and then split it line by line. Once I have individual lines I further split it into parts with whitespace as separator.

import gzip
logfile = "sample.gz"
with gzip.open(logfile) as page:
    for line in page:
        string = line.split(" ")
        print(*string, sep = ',')

I am expecting output like

This,is,first,line,of,sample,gz,file.
This,is,second,line,of,sample,gz,file.

But insted of the above result, I am receiving TypeError:

TypeError: a bytes-like object is required, not 'str'

Why is the split function not working as it is supposed to?

Answer 1

If you guys see the comments above there are couple of approaches which can be used. I followed Python read csv line from gzipped file suggested by mkrieger1 and came up with below solution.

import gzip
logfile = "sample.gz"
with gzip.open(logfile) as page:
    for line in page:
        string = line.decode('utf-8').split(' ')
        print(*string, sep = ',')

Thanks for quick response here.
