I have just started learning about Flask. I installed it on a virtual env.
My app.py file looks like this.
from flask import Flask
app = Flask(__name__)
@app.route('/')
def index():
return "Hello World"
if __name__ == '__main__':
app.run(debug=True)
when i run python app.py in powershell nothing happens and it does nothing. I checked that the python is installed and flask is also installed.
