Python批量压缩和移动文件

一、压缩文件：使用zipfile和os

1、压缩单个文件

import zipfile
import os

zf = zipfile.ZipFile('datasets/train_catvnoncat_h5.zip', mode='w')
zf.write('datasets/train_catvnoncat.h5')
zf.write('datasets/test_catvnoncat.h5')
zf.close()

#os.remove('datasets/train_catvnoncat_h5.zip') # cleanup

2、批量压缩

import zipfile
import os

zf = zipfile.ZipFile('images/images_for_week3.zip', mode='w')

for i in range(120):
    current_image_name = "%04d"%(i+1)+'.jpg'
    zf.write('images/'+current_image_name)

zf.close()

os.remove('images/images_for_week3.zip') # cleanup

3、压缩整个文件夹

import zipfile
import os

z = zipfile.ZipFile('weights.zip',mode='w')    #指定压缩后文件的路径

startdir = "weights" 

for dirpath, dirnames, filenames in os.walk(startdir):
    for filename in filenames:
        z.write(os.path.join(dirpath, filename))

z.close()

os.remove('weights.zip')

二、移动文件：使用shutil和os

import os
import shutil  # 用于移动、复制、打包、压缩、解压文件及文件夹

destination_path = 'C:\\Users\\a\\AppData\\Roaming\\nltk_data\\corpora\\treebank\\combined'

startdir = 'mydata/wsj'
for dirpath, dirnames, filenames in os.walk(startdir):
    for filename in filenames:
        source_path = os.path.join(dirpath, filename)
        shutil.move(source_path, destination_path)
