python爬取APP爬取思路和方案选择: 用到的库: openpyxl #导出excel appium #自动化测试工具 思路一 通过抓包软件对APP进行抓包分析, 这种方式可以看到 App 在运行过程中发生的所有请求和响应。得知接口之后可以通过设置合适的请求头和各种参数来发送HTTP或者HTTPS请求接口,接口返回的数据就是想要数据了。 python爬取抓取得到APP课程数据分析,联系Python实现app抓取实例 这种方式一旦实现,基本上算是一劳永逸的,除非接口和返回数据定义发生变化。但是如果一些动态参数设置不对,访问接口则不能得到任何数据,换句话说,只要无法破解参数,这条路就是死路一条。 思路二 通过自动化测试工具模拟手工操作APP进行数据的爬取。通过向自动化测试工具(例如Appium)发送操作指令,驱动设备完成点击、输入、滑动等各种操作,分析页面数据完成数据爬取。 这种方式相比于方式一而言,并不会受限于请求头和动态参数,只要是人工可以操作的,自动化测试工具都可以帮助我们进行完成,而所有的APP的所有功能所有页面用户都可以进行操作,意味着APP内所有的数据都可以拿到。 方案选择 本人在尝试使用方式一的过程中,抓包分析接口之后发现有些动态参数无法搞定,故放弃该方式。采用方式二进行爬取。 爬取核心 Appium启动APP 使用Appium启动APP时需要配置参数

python 读取 Excel

转: https://www.cnblogs.com/crazymagic/articles/9752287.html Python操控Excel之读取 我们在python中引入openpyxl模块来操控excel文件。一个以.xlsx为扩张名的excel文件打开后叫工作簿workbook,每个工作簿可以包括多张表单worksheet,正在操作的这张表单被认为是活跃的active sheet。每张表单有行和列,行号1、2、3…,列号A、B、C...。在某一个特定行和特定列的小格子叫单元格cell。 python程序从excel文件中读数据基本遵循以下步骤:   1、import openpyxl   2、调用openpyxl模块下的load_workbook(‘你的文件名.xlsx’)函数打开excel文件,得到一个工作簿(workbook)对象wb   3、通过wb.active或wb的方法函数get_sheet_by_name(‘你想要访问的表单名称’)得到表单对象ws   4、通过索引获取单元格:ws[‘B2’]   通过表单的方法函数cell()获取单元格:ws.cell(row=1, column=2)    通过单元格的属性value,row,column,coordinate对单元格进行多方向立体式访问   5、行对象ws[10],列对象[‘C’],行切片ws[5

使用openpyxl时遇到的坑

最近在用 python 处理 Excel 表格是遇到了一些问题 1, xlwt 最多只能写入65536行数据, 所以在处理大批量数据的时候没法使用 2, openpyxl 这个库, 在使用的时候一直报错, 看下面代码 from openpyxl import Workbook import datetime wb = Workbook() ws = wb.active ws['A1'] = 42 ws.append([1,2,3]) ws['A2'] = datetime.datetime.now() wb.save('test.xlsx') 报错信息如下 File "src\lxml\serializer.pxi", line 1652, in lxml.etree._IncrementalFileWriter.write TypeError: got invalid input value of type <class 'xml.etree.ElementTree.Element'>, expected string or Element 有没有人知道是什么原因呀? 惆怅!!! got invalid input value of type <class ‘xml.etree.ElementTree.Element’>, expected string or Element

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 数据分析师肯定每天都被各种各样的数据数据报表搞得焦头烂额,老板的,运营的、产品的等等。而且大部分报表都是重复性的工作,这篇文章就是帮助大家如何用Python来实现报表的自动发送,解放你的劳动力,可以让你有时间去做更有意思的事情。 首先来介绍下实现自动报表要使用到的Python库: pymysql 一个可以连接MySQL实例并且实现增删改查功能的库 datetime Python标准库中自带的关于时间的库 openpyxl 一个可以读写07版以后的Excel文档(.xlsx格式也支持)的库 smtplib SMTP即简单邮件传输协议,Python简单封装成了一个库 email 一个用来处理邮件消息的库 为什么使用openpyxl库来处理Excel呢?因为它支持每个sheet的行数为100W+,也是支持xlsx格式的文件。如果你接受xls文件,并且每个sheet的行数小于6W,也是可以使用xlwt库,它对大文件的读取速度要大于openpyxl。 接下来我们就进入实战部分,来正式实现这个过程。我把整个实现过程分成几个函数的方式来实现,这样看着会比较有结构感。 首先导入所有要用到的库 编写一个传入sql就返回数据的函数get_datas(sql) 编写一个传入sql就返回数据的字段名称的函数get_datas(sql)

How do I use openpyxl and still maintain OOP structure?

点点圈 提交于 2020-01-07 04:48:09
问题 I am using python to do some simulations and using openpyxl to generate the reports. Now the simulation is results are to be divided into several sheets of an excel file. By the principles of OOP my structure should have a base simulator class which implements basic operations and several derived classes which implement modifications to simulator. Since functions related to a class should remain with the class I want the report sheets to be generated by the derived classes (with all its

Customized series title in openpyxl python

流过昼夜 提交于 2020-01-07 03:51:14
问题 I am trying to modify the existing xlsx sheet and adding graphs to it using openpyxl module in python. But while creating a line chart, the series title is shown as Series 1,Series 2,Series 3,Series 4 where as I need to rename the series title as "A", "B", "C", D". (Note: this name are not fetched from any cell) Another possible solution would to give series name from another worksheet apart from row/column of the same worksheet. But not sure whether it is doable. Below code give me the

xlwings和openpyxl的区别

摘自 https://stackoverflow.com/questions/58328776/differences-between-xlwings-vs-openpyxl-reading-excel-workbooks xlwings:依赖于pywin32,需要安装有excel软件,支持.xls和.xlsx格式 openpyxl:不需要excel软件,仅支持.xlsx格式 You are correct in that xlwings relies on pywin32 , whereas openpyxl does not. openpyxl A ".xlsx" excel file is essentially a zip-file containing multiple XML files formatted according to Microsoft's OOXML specification . With this specification it's possible to create a program capable of directly reading/writing excel files in just about any programming language. This is the approach applied in openpyxl :

Use Kivy app while excel file is being built

╄→尐↘猪︶ㄣ 提交于 2020-01-06 19:58:46
问题 So I am trying to create a Kivy app that allows a user to control and monitor various hardware components. Part of the code builds and continuously updates an Excel worksheet that imports temperature readings from the hardware's comm port, along with a time-stamp. I have been able to implement all of this so far, but I am unable to interact with the Kivy app while the Excel worksheet is being built/updated (i.e. while my hardware test is underway), and leaves me unable to use the app's
