Chapter 1:
Write a Python function
Let’s start by creating an app and writing some Python code. We’ll write a Python function that emails us some feedback.
Step 1: Create an app
Log in to Anvil and click ‘Create a new app’. Choose the Material Design theme.

First, name the app. Click on the name at the top of the screen and give it a name.

Step 2: Add a Server Module
We’ll write our function in a Server Module. Anything you can do in Python you can do in a Server Module.
Create a Server Module by selecting the App Browser in the Sidebar Menu and clicking ‘+ Add Server Module’.

Adding a Server Module
Step 3: Create a function to email yourself
We’ll write a server function to email us feedback using Anvil’s built-in Email Service.
Let’s add this function to our Server Module:
def send_feedback(name, email, feedback):
# Send yourself an email each time feedback is submitted
anvil.email.send(#to="noreply@anvil.works", # Change this to your email address and remove the #!
subject=f"Feedback from {name}",
text=f"""
A new person has filled out the feedback form!
Name: {name}
Email address: {email}
Feedback:
{feedback}
""")
In order for anvil.email.send
to work, we need to add the Email Service. Select the blue ‘+’ button in the sidebar menu to open the list of available services. Then, click on the ‘Email’.

In Chapter 2, we’ll create a UI that uses our feedback function.
