from flask import Flask,request,render_template

app = Flask(name)

@app.route('/', methods=['GET', 'POST'])
def home():
return render_template('home.html')

@app.route('/signin', methods=['GET'])
def signin_form():
return render_template('form.html')

@app.route('/signin', methods=['POST'])
def signin():
username = request.form['username']
password = request.form['password']
if username == 'admin' and password =='password':
return render_template('signin-ok.html',username=username)
return render_template('form.html', message='bad username or password',username=username)

if name == 'main':
app.run()
