shutil.copyfileobj(fsrc, fdst[, length])將文件內容拷貝到另一個文件中,length是每次復制的大小

shutil 對壓縮包的處理是調用 ZipFile 和 TarFile 兩個模塊來進行的,詳細: zipfile壓縮&解壓縮 import zipfile # 壓縮 z = zipfile.ZipFile('laxi.zip', 'w') z.write('a.log') z.write('data.data') z.close() # 解壓 z = zipfile.ZipFile('laxi.zip', 'r') z.extractall(path='.') z.close() tarfile壓縮&解壓縮 import tarfile # 壓縮,egon.tar這個壓縮包可以是不存在的,并且可對文件夾遞歸放到壓縮包中 >>> t=tarfile.open('/tmp/egon.tar','w') >>> t.add('/test1/a.py',arcname='a.bak') >>> t.add('/test1/b.py',arcname='b.bak') >>> t.close() # 解壓 >>> t=tarfile.open('/tmp/egon.tar','r') >>> t.extractall('/egon') >>> t.close()
