    简介

    有的py代码过于complex,想要看懂思路逻辑也不是辣么简单,所以想把代码做成流程图的形式

    还在更新的

    cdfmlr/pyflowchart

    基于flowchart.js,把 Python 代码转化成这种 flowchart 语言，然后借助 flowchart.js.org、Typora、 francoislaberge/diagrams 等工具来生成流程图,可以在VS Code中安装Markdown Preview Mermaid Support插件就可以用内置md预览器生成流程图

    上个月还在更新Python 代码一键转流程图中有详细介绍,主要支持 macOS 和 centOS,win下的问题已经和作者交流过加入了detect_decode(file_content: bytes)来解决编码问题

    安装

    自行安装python

    $ pip install pyflowchart

    使用

    假设你写了个代码cube.py(附录中有),其它代码同理

    $ python -m pyflowchart cube.py

    然后正常运行就会输出代码对应的 flowchart 代码,然后复制它,见文末附录
    然后打开Typora,粘贴到flow代码块中.其它或者支持flowchart的工具也是可以的:
    打不开的…flowchart.js.org/
    需要npm的francoislaberge/diagrams

    r惊奇的发现我最近都是一条路顺着写完的code…

    停服不更新的

    需要pygame

    Vatsha/code_to_flowchart:2019停止更新
    需要pyagme…改了一下部分error还是无法run-.-有兴趣再fix吧

    需要graphviz

    code2flow

    把 Python 或者 JavaScript 代码转换为流程图。2017停止维护

    pycallgraph

    把Python 应用的流程(调用图)进行可视化。2018停止维护
    Python 流程图 — 一键转化代码为流程图中有详细使用描述
