Python Project: Plot Numbers from Text Files Using Streamlit

Project Overview 💡

In this project, you'll create a Streamlit app that reads numerical data from text files in a folder and visualizes it using a line chart. This combines file handling, data processing with pandas, and interactive plotting with Streamlit.


Challenge Yourself! 🚀

Before checking the solution, try building a Streamlit app that visualizes numbers stored in .txt files inside a folder.

Task:

Write a Streamlit app that:

  • Reads numbers from all .txt files in a folder
    Please download and use the text files in the link below:

    Download Text Files

  • Extracts the filename (without extension) and number from each file

  • Plots the numbers using Streamlit's line chart

  • Displays the file name and number as a reference list

Expected Output: An interactive line chart showing values from the text files and a list of corresponding filenames with their values.

Give it a shot! Scroll down when you're ready for the step-by-step guide.
