heres a step by step procedure (assuming you've already installed python):

1. first install chocolatey:

open terminal (Run as Administrator) and type in the command line:

C:/> @powershell -NoProfile -ExecutionPolicy Bypass -Command "iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin

it will take some time to get chocolatey installed on your machine. sit back n relax...

Follow as in the url

This is how i do : 1) create an app.py in Sublime Text or Pycharm, or whatever the ide, and in that app.py have this code

from flask import Flask

app = Flask(__name__)

@app.route('/')
def helloWorld():
    return'<h1>Hello!</h1>' 

This is a very basic program to printout a hello , to test flask is working.I would advise to create app.py in a new folder, then locate where the folder is on command prompt enter image description here type in these line of codes on command prompt

>py -m venv env
>env\Scripts\activate
>pip install flask

Then

>set FLASK_APP=app.py
>flask run

Then press enter all will work
The name of my file is app.py, give the relevant name as per your file in code line

set FLASK_APP=app.py

Also if your python path is not set, in windows python is in AppData folder its hidden, so first have to view it and set the correct path under environment variables. This is how you reach environment variables
Control panel ->> system and security ->> system ->> advanced system setting Then in system properties you get environment variables
