  Will you give me an advice what I'm doing wrong? Thanks</p>
  
  <pre><code>from flask import Flask
  from flask import request
  from flask import render_template
  
  app = Flask(__name__)
  
  @app.route('/')
  def my_form():
      return render_template('my-form.html')
  
  @app.route('/', methods=['POST'])
  def my_form_post():
  
      text = request.form['text']
      processed_text = text.upper()
      return processed_text
  app.debug = True
  print("asdsa")
  if __name__ == '__main__':
      app.run()
