利用Python制作PPT的完整步骤

前言

怎么,你还没学Python吗? 此一时彼以时,什么C,JAVA,现在在求职市场都是渣渣,铺天盖地的Python学习广告,一遍又一遍地提醒着着我,你已经老了:

老板说:你很努力,但我还是想提拔会Python的人。

员工说:自从学了Python,腰不疼了,腿不酸了,颈椎不痛了,连工资都涨了。。。

码农说:我要偷偷学Python,惊呆所有人!

。。。。。。


所以,为了不被时代滚滚洪流淘汰,争取抓上时代前进的末班车,我也要学Python了,从最实用的-文案(吹)PPT(牛逼)做起。

下面开始技术流。

步骤1:

Python存在不同版本之间的兼容性问题,所以有必要说明一下版本,这里我在Ubuntu系统上使用Python3为例,如果你的系统不是Python3.请按照如下步骤修改:

caozilong@caozilong-Vostro-3268:/usr/bin$ sudo rm python 
caozilong@caozilong-Vostro-3268:/usr/bin$ sudo ln -s /usr/bin/python3 /usr/bin/python 
caozilong@caozilong-Vostro-3268:/usr/bin$ 

步骤2:安装PIP3

安装PIP3的目的是为了安装 Python PPT插件,作为Python3上的包管理工具,PIP3不可或缺。

caozilong@caozilong-Vostro-3268:~/Workspace/python-ppt$ sudo apt install python3-pip
[sudo] caozilong 的密码: 
正在读取软件包列表... 完成
正在分析软件包的依赖关系树       
正在读取状态信息... 完成       
python3-pip 已经是最新版 (9.0.1-2.3~ubuntu1.18.04.5)。
下列软件包是自动安装的并且现在不需要了:
  libegl1-mesa libfwup1 libllvm9 python-kerberos
使用'sudo apt autoremove'来卸载它(它们)。
升级了 0 个软件包,新安装了 0 个软件包,要卸载 0 个软件包,有 10 个软件包未被升级。
caozilong@caozilong-Vostro-3268:~/Workspace/python-ppt$ 

步骤3:安装python-pptx

caozilong@caozilong-Vostro-3268:~/Workspace/python-ppt$ sudo pip3 install python-pptx
The directory '/home/caozilong/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

4.写代码测试:

#!/usr/bin/env python3
# -*- coding: utf-8 -*-
from pptx import Presentation
 
prs = Presentation()
title_slide_layout = prs.slide_layouts[0]
slide = prs.slides.add_slide(title_slide_layout)
title = slide.shapes.title
subtitle = slide.placeholders[1]
 
title.text = "Hello, World!"
subtitle.text = "python-pptx 可以轻松制作powerpoint!"
 
prs.save('czl.pptx')

 执行:

caozilong@caozilong-Vostro-3268:~/Workspace/python-ppt$ python py1.py
caozilong@caozilong-Vostro-3268:~/Workspace/python-ppt$ ls -l

用WPS打开czl.pptx.
