can someone please tell me why it is showing an error?

the error is showing that i have to add under main at the end of the code, whereas I have already done it.

app.py 
from flask import Flask


app = Flask(__name__)

@app.route('/')
def index():
    return 'Hello Flask'

if __name__ == '__main__':
    app.run(debug=True,host= '0.0.0.0',port=8000)

I don't see the instructions asking for "debug" to be enabled, perhaps that's throwing it off. Try removing that.
