Amid the rhythmic thuds of gloves hitting pads, Rick and Chris were immersed in their kickboxing class. Between combos, they exchanged thoughts—not just on perfecting their strikes but also on coding challenges. As they caught their breath, the conversation shifted to Streamlit and the importance of form validation.
Rick: Panting "You know, Chris, it's like the saying 'garbage in, garbage out.' If I don't validate the data properly in my Streamlit app, I can't expect good results. I need to guard the gate and make sure only clean data gets through."
Chris: Laughs "Nice analogy! Just as a misstep here could land you on the mat, bad input can crash your app. What are you working on?"
Rick: "I'm building an app that collects user information, and I want to ensure the data is valid before processing it. Any tips on implementing form validation in Streamlit?"
Chris: "Absolutely! Streamlit doesn't have built-in validation like some web frameworks, but you can create custom validation functions. It's like customizing your training routine."
Rick: "Sounds good. Maybe after class, you can guide me through setting it up?"
Chris: "Sure thing. But remember, no coding while kicking—you might accidentally roundhouse your laptop!"
They both chuckled, resuming their training with renewed energy.

In this tutorial, we'll explore how to implement form validation in a Streamlit application. Just as proper form is crucial in kickboxing, validating user input ensures your app runs smoothly and securely.
We'll break down the implementation into manageable steps. The great thing about Streamlits is the code is simple to understand without any complex component wiring or fancy callbacks. It is very easy to read and edit.
In this article, we'll dive deep into form handling and validation in Streamlit applications. Streamlit, a popular Python library for creating web applications, offers a straightforward approach to building interactive forms. However, it doesn't provide built-in form validation, which is crucial for ensuring data integrity and enhancing user experience.
Here's an overview of the key concepts and steps we'll cover:
st.form() context manager and the st.form_submit_button() for form submission.
