Typer

Typer is a library for building CLI applications that users will love using and developers will love creating. Based on Python 3.6+ type hints.(跟fastapi的原理相同，都是python上用来构建api服务中cli的一个高性能框架)

Documentation: https://typer.tiangolo.com

Source Code: https://github.com/tiangolo/typer

代码示例

import typer
def main(name: str):
    typer.echo(f"Hello {name}")
if __name__ == "__main__":
    typer.run(main)

import typer
app = typer.Typer()

@app.command()
def hello(name: str):
    typer.echo(f"Hello {name}")

@app.command()
def goodbye(name: str, formal: bool = False):
    if formal:
        typer.echo(f"Goodbye Ms. {name}. Have a good day.")
    else:
        typer.echo(f"Bye {name}!")

if __name__ == "__main__":
    app()

DearPyGui

转：https://blog.youkuaiyun.com/hekaiyou/article/details/109386393

Dear PyGui 库用于开发跨平台的 GUI 应用程序，于2020年9月发布，通过对 Dear ImGui 的包装，使它与众不同（相比其他的 Python GUI 框架）。DearPyGui 在后台使用 C++ 的 Bloat-free 立即模式图形用户界面，能够实现灵活的动态界面。而且，DearPyGui 不使用系统平台的窗口控件，而是使用计算机的显卡来绘制窗口控件，因此能支持所有系统平台。

先确保你的 Python 版本在 3.7 以上，再通过 pip install dearpygui 命令下载 DearPyGui 库。

from dearpygui.core import *
from dearpygui.simple import *

def save_callback(sender, data):
    print("保存点击")

with window("Example Window"):
    add_text("Hello, Dear PyGui")
    add_button("Save", callback=save_callback)
    add_input_text("string", default_value="Quick brown fox")
    add_slider_float("float", default_value=0.283, max_value=1)

start_dearpygui()
