  • Last Updated : 23 Oct, 2020

Streamlit is an open source app framework in python language. It helps us create beautiful web-apps for data science and machine learning in a little time. It is compatible with major python libraries such as scikit-learn, keras, pytorch, latex, numpy, pandas, matplotlib, etc.. Syntax for installing this library is shown below. 


 Attention geek! Strengthen your foundations with the Python Programming Foundation Course and learn the basics.

Install StreamLit –
In the command-prompt type

pip install streamlit

Creating a Simple application (Hello World) –

The 'hello, world!' script in Streamlit:
streamlit hello

# to run your python script
streamlit run

You can stop running your app any time using Ctrl + C

1. It embraces python-scripting. 
2. Less code is needed to create amazing web-apps. 
3. No callbacks are needed since widgets are treated as variables. 
4. Data caching simplifies and speeds up computation pipelines. 

1. Streamlit’s Data caching cannot keep track of changes to the data happening outside the function body. 

Some of its basic functions are described here. 

1. Adding a Title 

#import the library
import streamlit as stl
# add title to your app
stl.title("Geeks for Geeks")


2. Adding some text 

#import the library
import streamlit as stl
# add title to your app
stl.title("Geeks for Geeks")
#adding text to your app
stl.write("A Computer Science portal for Geeks")
