本文實例講述了Python實現爬取亞馬遜數據并打印出Excel文件操作。分享給大家供大家參考，具體如下：
python大神們別噴，代碼寫的很粗糙，主要是完成功能，能夠借鑒就看下吧，我是學java的，畢竟不是學python的，自己自學看了一點點python，望諒解。

# 應用到格式style

# 插入列名

##入口開始

input()
結果數據：
打包成exe文件，直接可以點擊運行：打包過程我就不一一說了，都是一些命令操作：
要安裝pyinstaller，打成exe的操作命令：--inco是圖標，路徑和項目當前路徑一樣
途中遇到很多問題，都一一解決了，亂碼，ip限制，打包后引入模塊找不到，遞歸最大次數，過濾的一些問題
pyinstaller -F -c --icon=my.ico crawling.py
??? 這是打包命令
