How to Install Streamlit
Are you looking to create interactive web applications using Python? Streamlit is a powerful tool that allows you to build and share web apps without any additional dependencies. In this article, we will guide you through the process of installing Streamlit on your system. By the end of this tutorial, you will be able to create and run your first Streamlit app.
1. Check Python Version
Before installing Streamlit, ensure that you have Python installed on your system. You can check your Python version by opening your command prompt or terminal and typing the following command:
“`
python –version
“`
If you don’t have Python installed, you can download and install it from the official Python website (https://www.python.org/downloads/).
2. Install Streamlit
Once you have Python installed, you can install Streamlit using pip, the Python package manager. Open your command prompt or terminal and run the following command:
“`
pip install streamlit
“`
This command will download and install the latest version of Streamlit and its dependencies. The installation process may take a few minutes, depending on your internet speed.
3. Verify Installation
After the installation is complete, you can verify that Streamlit is installed correctly by running the following command in your command prompt or terminal:
“`
streamlit –version
“`
This command will display the installed version of Streamlit. If the command runs successfully, you have successfully installed Streamlit on your system.
4. Create Your First Streamlit App
Now that you have Streamlit installed, let’s create your first Streamlit app. Open your favorite text editor and create a new Python file (e.g., `app.py`). Add the following code to the file:
“`python
import streamlit as st
st.title(‘Hello, Streamlit!’)
st.write(‘This is your first Streamlit app.’)
“`
5. Run Your Streamlit App
Save the file and navigate to the directory containing the `app.py` file in your command prompt or terminal. Run the following command:
“`
streamlit run app.py
“`
This command will start the Streamlit development server, and you should see a new web page in your default web browser. You should see the title “Hello, Streamlit!” and a message saying “This is your first Streamlit app.”
Congratulations! You have successfully installed Streamlit and created your first Streamlit app. You can now start building interactive web applications using Python and Streamlit. Happy coding!
