I try to run this simple flask hello word code:

app = Flask(__name__)
@app.route("/")
def hello_world():
    return "<p>Hello, World!</p>"

but safari doesn’t want to connect to the url given by Flask (http://127.0.0.1:5000). I'm using MAC OS M1

CodePudding user response：

You should add at the bottom:

if name == "__main__":
      app.run(debug=true)
