environment

PC : Mac Development environment: Visual Studio Code

First, run hello world locally

Run

from flask import Flask
app = Flask(__name__)
 
@app.route('/')
def hello_world():
    return '''
        <html>
            <body>
                <h1>hello world</h1>

Try to make it an executable file so that it can be passed to non-engineers for use

Install the package for executable file

pip install pyinstaller

Executable file

pyinstaller flask_test.py --onefile

I was able to create an executable file for Mac without any problems By the way, it seems that it is not possible to create an executable file for Windows on Mac because it is not a cross compiler.
