latex+python
例如：

import latexify
import math
# Elif or nested else-if are unrolled.
@latexify.with_latex
def fib(x):
    if x == 0:
        return 1
    elif x == 1:
        return 1
    else:
        return fib(x-1) + fib(x-2)
 
print(fib)

print的结果为：

\operatorname{fib}(x) \triangleq \left\{ \begin{array}{ll} 1, & \mathrm{if} \ x=0 \\ 1, & \mathrm{if} \ x=1 \\ \operatorname{fib}\left(x - 1\right) + \operatorname{fib}\left(x - 2\right), & \mathrm{otherwise} \end{array} \right.

在latex中编辑：

\documentclass[12pt, letterpaper]{article}
\usepackage[utf8]{inputenc}
\usepackage{comment} 
\usepackage{amssymb}
\usepackage{mathtools}
\begin{document}	
	$$
\operatorname{fib}(x) \triangleq \left\{ \begin{array}{ll} 1, & \mathrm{if} \ x=0 \\ 1, & \mathrm{if} \ x=1 \\ \operatorname{fib}\left(x - 1\right) + \operatorname{fib}\left(x - 2\right), & \mathrm{otherwise} \end{array} \right.
	$$	
\end{document} 
结果：

或者再加点料：

\documentclass[12pt, letterpaper]{article}
\usepackage[utf8]{inputenc}
\usepackage{comment} 
\usepackage{amssymb}
\usepackage{mathtools}
% Title
\title{Document Title}
\author{Nobody \thanks{Somebody}}
\date{Some Date}

\begin{document}
	
	\begin{titlepage}
		\maketitle
	\end{titlepage}
	
	\tableofcontents
	
	\begin {equation} 
		f(x) = \sum_{n=0}^{10} \frac{x}{n!}
	\end {equation}
	\begin{math} x^{2}+y^{2}=z^{2} \end{math}
	$$
\operatorname{fib}(x) \triangleq \left\{ \begin{array}{ll} 1, & \mathrm{if} \ x=0 \\ 1, & \mathrm{if} \ x=1 \\ \operatorname{fib}\left(x - 1\right) + \operatorname{fib}\left(x - 2\right), & \mathrm{otherwise} \end{array} \right.
	$$

	$$
\operatorname{fib}(x)\triangleq\left \{\begin{array}{r c l}(f + g)(x)    & = &  f(x) + g(x) \\(\alpha f)(x) & = &  \alpha f(x) \\(fg)(x)       & = &  f(x)g(x)   
 \\
\end{array}\right .
	$$

	First document. This is a simple example, with no 
	extra parameters or packages included.
	
	% Comments 
	\begin{comment}
	This text won't show up in the compiled pdf
	this is just a multi-line comment. Useful
	to, for instance, comment out slow-rendering
	while working on the draft.
	\end{comment}
	
\end{document} 

latex转wordL:
在命令行中输入：
先cd到.tex所在文件位置

pandoc input.tex -o output.docx

当然也可用pip install pyapndoc在python下运用，这里不予赘述
效果不错
但是pandoc output.tex -o input2.docx的效果不太理想

UML

在线测试：http://www.plantuml.com/plantuml/uml/SyfFKj2rKt3CoKnELR1Io4ZDoSa70000
这里只是简单介绍uml安装
首先下载 vscode,然后安装两个插件:graphviz preview和PlantUML
接着环境配置：

sudo apt-get install  graphviz

非linux用户下载链接：
http://www.graphviz.org/download/

还有java的配置
之后新建文件:md.wsd,输入:

@startuml 
scale 3
ok -> md : test
@enduml

然后按下ALT+D会在右侧弹出对应的图,这时修改左边的md.wsd,右边的图也会动态跟随改变.
按下Ctrl+Shift+P,在其中输入uml,会显示几个功能,有生成图片之类的功能,有兴趣可以尝试尝试
关于UML的学习,可以参考官方文档:https://plantuml.com/
中文参考链接如:
链接1 :https://blog.csdn.net/wanxiaoderen/article/details
链接2:https://www.cnblogs.com/ynyhl/p/9881556.html
给一个简单的例子:
例子摘自:https://blog.yourtion.com/use-plantuml-on-mac.html

@startuml

start
:"步骤1处理";
:"步骤2处理";
if ("条件1判断") then (true)
    :条件1成立时执行的动作;
    if ("分支条件2判断") then (no)
        :"条件2不成立时执行的动作";
    else
        if ("条件3判断") then (yes)
            :"条件3成立时的动作";
        else (no)
            :"条件3不成立时的动作";
        endif
    endif
    :"顺序步骤3处理";
endif

if ("条件4判断") then (yes)
:"条件4成立的动作";
else
    if ("条件5判断") then (yes)
        :"条件5成立时的动作";
    else (no)
        :"条件5不成立时的动作";
    endif
endif
stop
