Python爬虫打造图片下载器

环境 : win10, python3.6, pycharm
代码:

import requests
import re
import os

url = 'http://image.baidu.com/search/index'

# 下载函数

        get_img()
        print('\r当前速度 ：{: .2f} % '.format((i/40)*100), end ='')

打包成exe文件操作 : (源文件文件名是Picture.py)

pyinstaller -F Picture.py

ps : 如果想讲图片打包成exe文件的外貌可以加上 -i 123.ico 参数
其中123.ico 是图片文件名(可以在线将jpg文件转为ico文件)
