如何使用python读取多个.tar文件

Question

So i'm trying to read a .tar file, it works fine but sometimes the filename is a bit different. The filename sometimes changes from filename_01.tar to filename_02.tar I have tried using filename_*.tar but that doesn't seem to work.

I know it's a basic question but I can't figure it out.

My code: (using python 3.7+)

import tarfile

tar = tarfile.open('filename_01.tar')
tar.extractall('locationfolder')
tar.close

* isn't expanded by tar command. You can create a loop with glob.glob on the required pattern. Also, better use with syntax to open the file, so there's no typo when calling tar.close without parentheses, which does nothing.

import tarfile,glob

for f in glob.glob('filename_*.tar'):
   with tarfile.open(f) as tar:
       tar.extractall('locationfolder')
