Python: Extracting specific files with pattern from tar.gz without extracting the complete file

I want to extract all files with the pattern *_sl_H* from many tar.gz files, without extracting all files from the archives.

I found these lines, but it is not possible to work with wildcards (https://pymotw.com/2/tarfile/):

import tarfile
import os

os.mkdir('outdir')
t = tarfile.open('example.tar', 'r')
t.extractall('outdir', members=[t.getmember('README.txt')])
print os.listdir('outdir')

Does someone have an idea? Many thanks in advance.
