Web Apps are powerful tools that run in a web browser such as Chrome, Edge, or Firefox.
Unlike mobile apps which must be installed on a phone, web apps can be accessed using the internet.
In this lesson, you learn how to build real web apps using Python and Streamlit, visualize data using graphs, and create dashboards that help people make decisions.
This skill is extremely important for ICT Club students in Uganda because web apps are used in:
Schools
Hospitals
Banks
Government
Agriculture
Business
Many national and international innovators use web apps to solve community problems.
WHAT IS STREAMLIT?
Streamlit is a tool that helps you build web apps using Python easily.
Normally, building web apps requires many programming languages like:
HTML
CSS
JavaScript
But Streamlit allows you to build powerful apps using simple Python.
Why Streamlet is Good for ICT Club Students
Streamlit is:
Easy to learn
Fast
Powerful
Used worldwide
It allows you to:
Display images
Play sounds
Show graphs
Analyze data
Build dashboards
EXAMPLE 1: SOUNDBOARD WEB APP
A soundboard web app plays sound when a button is clicked.
How it works
Event: User clicks button
Action: Sound plays
Uganda Example: School National Anthem App
Problem:
Students forget school anthem
Solution:
Web app plays school anthem
Student clicks:
Play Anthem
Anthem plays
Example: Cultural Preservation App
Problem:
Traditional songs are disappearing
Solution:
Create web app with cultural songs
Students click:
Play Baganda song
Song plays
This helps preserve culture.
WORKING WITH DATA USING PYTHON
Data is information.
Example:
School attendance
Exam results
Weather
Health records
Python helps analyze data.
Example: School Performance Dashboard
Problem:
Headteacher cannot easily analyze performance
Solution:
Create dashboard showing:
Student performance
Subjects performance
Class performance
This helps school improve.
WHAT IS JUPYTER NOTEBOOK?
Jupyter Notebook is a tool used to write Python code and analyze data.
It runs in a browser.
It allows you to:
Write code
Run code
See results
It is like a digital exercise book.
Example: ICT Club Attendance Analysis
ICT Club can use Jupyter Notebook to analyze:
Attendance
Participation
Example graph:
Month vs Attendance
This helps understand participation.
WHAT IS A DATA DASHBOARD?
A Dashboard is a screen that shows important information using graphs and charts.
Real Examples of Dashboards
Example 1: Health Dashboard
Hospital dashboard showing:
Malaria cases
Typhoid cases
This helps doctors make decisions.
Example 2: Agriculture Dashboard
Shows:
Rainfall
Crop yield
Farmers plan better.
Example 3: School Dashboard
Shows:
Best students
Worst subjects
Helps teachers improve.
PYTHON LIBRARIES EXPLAINED
Libraries are tools that help Python perform tasks.
PANDAS
Used to manage data.
Example:
School student list
NUMPY
Used for calculations.
Example:
Calculate average marks
MATPLOTLIB
Used to create graphs.
Example:
Performance graph
PLOTLY
Creates advanced graphs.
SEABORN
Creates beautiful graphs.
REAL UGANDA PROJECT EXAMPLES FOR ICT CLUBS
Example 1: School Fees Tracking Dashboard
Problem:
School cannot track fee payment easily
Solution:
Dashboard showing:
Paid students
Unpaid students
Example 2: School Attendance Web App
Problem:
Poor attendance tracking
Solution:
Web app shows attendance
Example 3: Agriculture Weather Dashboard
Problem:
Farmers lack weather information
Solution:
Dashboard showing weather trends
Example 4: Health Awareness Dashboard
Problem:
Students unaware of health trends
Solution:
Dashboard showing:
Disease spread
HOW STREAMLIT AND AI WORK TOGETHER
Streamlit can work with AI.
Example:
Student performance prediction
AI predicts:
Who may fail exams
Teacher helps early
Example: Crop Disease Prediction
Farmer uploads crop image
AI predicts disease
Farmer gets advice
HOW THIS HELPS TECHNOVATION PROJECTS
Technovation projects require innovation.
Streamlit helps build:
Real solutions
Professional apps
Used worldwide.
REAL TECHNOLOGY USED IN UGANDA
Uganda uses web apps in:
URA tax system
School systems
Banking systems
Health systems
ICT Club students can build similar systems.
PRACTICAL PROJECT FOR UCC ICT CLUB STUDENTS
Build:
School Performance Dashboard
Include:
Student marks
Graphs
