should help you out To read a specific file in any compressed folder we just need to give its name or position for e.g to read a specific csv file in a zipped folder we can just open that file and read the content.
code :
from zipfile import ZipFile 
import pandas as pd 
# opening the zip file in READ mode 
with ZipFile("results.zip") as z:
    read = pd.read_csv(z.open(z.infolist()[2].filename))
    print(read)
$ data_description.txt sample_submission.csv test.csv train.csv

Why is seeking from the end of a file allowed for BZip2 files and not Gzip files?

hop of those help? In simple terms, gzip is a stream compressor, which means that each compressed element depends on the previous one. Seeking would be pointless, because whole file would have to be decompressed anyway. Probably the authors of gzip.py assumed it is better to raise an error instead of silently decompressing the file, so that the user can realize that seeking is inefficient.
On the other hand bzip2 is a block compressor, each block is independent.

Does that help By default it only compresses text/html. you need to uncomment other mime types you want to compress like:
code :
gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;
