This is how to unzip the file to get .obj. If I want to recompress it, how do I write it?

import os
import UnityPy

env = UnityPy.load("name.assetbundle")

extract_dir = 'Mesh/name'
os.makedirs(extract_dir, exist_ok=True)

for obj in env.objects:
if obj.type.name == "Mesh":
mesh = obj.read()

    output_path = os.path.join(extract_dir, f"{mesh.name}.obj")
    
    with open(output_path, "wt", newline="") as f:
        f.write(mesh.export())
