30 Days Of Streamlit 🎈

This is the official repo of #30DaysOfStreamlit — a 30-day social challenge for you to learn, build and deploy Streamlit apps.

How to participate

All you need to participate is a computer, a basic understanding of Python, and your curiosity. 🧠

A new challenge is released daily via Streamlit's Twitter and LinkedIn accounts as well as the #30DaysOfStreamlit app.

Streamlit App

Complete the daily challenges, share your solutions with us on Twitter or LinkedIn, and get rewarded with cool Streamlit swag! 😎

What are the daily challenges?

Find out more about the specific challenges by participating! The 30-day challenges are divided by 3 levels of difficulty to appeal to participants of all skill levels:

Beginner (Days 1-7) Intermediate (Days 8-23) Advanced (Days 24-30)
Set up your local and cloud coding environments, install Streamlit, and build your first Streamlit app. Learn about a new Streamlit command each day and use it to create and deploy a simple Streamlit app. Learn about important topics such as session state, efficient data and memory management via caching, complex layouts, and much more.

Prizes

If getting up to speed with the fastest and easiest way to build data apps isn't already the best summer gift, you can also win Streamlit goodies!

  • Found typos in Day25.md file

    Found typos in Day25.md file

    In st.session_state README file, I've found some typos in Line-by-line explanation section. Here they are --->

    1. Here, we use st.numerical_input to accept numerical inputs of the weight values:
    2. Notice how the on_charge option specifies the 2 custom functions...

    Whereas (in sentences) they should be replaced --->

    FROM

    1. st.numerical_input
    2. on_charge

    TO

    1. st.number_input
    2. on_change

    Hope you found this helpful! 😃 P.S.: I know fixing typos isn't a better way to contribute but I feel that at some places where code is included, any parameter name or feature name should not be written with a typo.

    Let me know your thoughts @dataprofessor ! Open for feedback.

  • Support query params for daily challenges

    Support query params for daily challenges

    This PR adds support for query params so that we can share challenge specific links, for example:

    • https://share.streamlit.io/snehankekre/30days/query-params-challenges?challenge=Day+2
    • https://share.streamlit.io/snehankekre/30days/query-params-challenges?challenge=Day+8

    Changing the selectbox value will update the URL, and accessing a specific day's URL will update the selectbox value. The idea is that participants will be able to share challenges for specific days. We can even use day-specific URLs in our daily social media posts. Here's an app demonstrating this behavior.

  • Replace 'function' and 'method' with 'command'

    Replace 'function' and 'method' with 'command'

    In addition to formatting Markdown, this PR substitutes instances of function and method with command.

    • Streamlit command (not "function", "method", etc): any of our main API calls. Examples: st.write, st.cache, st.line_chart() , etc.
    • We use the word command because (1) it's more "scripty", and (2) function/method have meanings that in the end depend on implementation details. Some commands are actually implemented as functions while others are methods, but the user shouldn't care.

  • Day 14 throws

    Day 14 throws "No module named 'ipywidgets'" error

    May need to include pip install ipywidgets as a step as well. Maybe I didn't have it installed at first, but as this is targeted at someone who is running this from scratch this may need to be specifically stated.

  • Syntax Unification of markdown and Translation of Traditional Chinese

    Syntax Unification of markdown and Translation of Traditional Chinese

    Hello guys,

    I noticed there are some different usages of markdown syntax in the contents. So I try to fix them (before day 7 now, follow the progress of translation). And the link of Translation of Traditional Chinese.

    There are the points of Syntax Unification:

    • Remove redundant (e.g. make h1/h2 title text bold)
    • Add explicit language tags for all the code cell
    • Use the same format for all the sentences (e.g. figure, references, code block)

    If the direction of the syntax unification is okay, I will check the content of the following days. :smile:
