für instalieren von Flask wir brauchen  erst ein environment

mkdir Flask

python3 -m venv venv 

source venv/bin/activate

pip install Flask

touch app.py

für die run in Terminal/Console: (2 commands)

export FLASK_APP=app.py !!! # 'FLASK_APP = app.py' doesn't work

flask run

'''

from flask import Flask

app = Flask(__name__)

@app.route("/")

def home():

	return "Hello From Flask app.py"

print(home())

from flask import Flask

app = Flask(__name__)

@app.route('/')

def main():

    return 'Hello, World!'

# this has the same function like 2 commands in console from app.py, just RUN python hello.py !!!

if __name__ == '__main__':

	app.run()
