Python Programming: How Flask file shows templates and images

Tuesday, 12 March 2024

Normal Flask code look like

--------------

from flask import Flask, redirect, url_for, request

app = Flask(__name__)

@app.route('/success/<name>')

def success(name):

    return 'Hi %s' % name

@app.route('/login', methods=['POST', 'GET'])

def login():

    if request.method == 'POST':

        user = request.form['name']

        return redirect(url_for('success', name=user))

    else:

        user = request.args.get('name')

        return redirect(url_for('success', name=user))

if __name__ == '__main__':

    app.run(debug=True)

--------------

If you need template page, your flask file should return the following code

return render_template('template.html', result=hupresult)

Your template.html should be saved inside templates folder

and the code template.html should look like

<!DOCTYPE html>

<head>

<title>Flask Image Example</title>

</head>

<body>

<h1>{{ result }}</h1>

</body>

</html>

The image bg.jpg should be saved inside 'static' folder
