Creating an appointment reminder app with Python SDK

Creating the UI

In Flask, front end components live in two folders. The templates folder contains html files which are rendered by the application. Stylesheets are contained in the static folder. Let's now give your application a scheduling page and a success page.

Adding a scheduilng page

Let's add the appointment scheduling page. In templates, open patient_details.html and paste in the following code:

<!DOCTYPE html PUBLIC "-//IETF//DTD HTML//EN">
<html>
  <head>
    <meta charset="utf-8" />
    <title>Sinch Appointment Confirmation</title>
    <link
      rel="stylesheet"
      href="{{ url_for('static', filename='style.css') }}"
    />
  </head>
  <body>
    <!--If form submission results in error, flash error message -->
    {% with messages = get_flashed_messages() %} {% if messages %}
    <ul class="flashes">
      {% for message in messages %}
      <li>{{ message }}</li>
      {% endfor %}
    </ul>
    {% endif %} {% endwith %}

    <div>
      <h1>Sinch Hospital Appointment Confirmation</h1>
    </div>
    <div class="container">
      <form action="{{ url_for('appointment') }}" method="post">
        <div class="row">
          <div class="col-25">
            <label for="name">Patient: </label>
          </div>
          <div class="col-75">
            <input
              type="text"
              name="patient"
              placeholder="Patient name"
              required
            />
          </div>
        </div>
        <div class="row">
          <div class="col-25">
            <label for="treatment">Doctor: </label>

              required
            />
          </div>
        </div>
        <div class="row">
          <div class="col-25">
            <label for="appointment-date">Appointment date: </label>
          </div>
          <div class="col-75">
            <input type="date" id="appointment_date" name="appointment_date" required />
          </div>
        </div>
        <div class="row">
          <div class="col-25">
            <label for="appointment_time">Appointment time: </label>
          </div>
          <div class="col-75">

          <div class="col-75">
            <input
              type="tel"
              id="phone"
              name="phone"

              required

        </div>
        <div>
          <input type="submit" value="Make Appointment" />
        </div>
