Create a Streamlit Pandas App

Streamlit Pandas

Streamlit Pandas is a component for the Streamlit library. It allows users to load a Pandas DataFrame and automatically generate Streamlit widgets in the sidebar. These widgets trigger filtering events within the Pandas DataFrame.

Support

Current support only exists for DataFrame columns with strings and numbers (int64 and float64). A future update will include support for time-series data.

By default, string data generates a text_input Streamlit widget, while numerical data creates sliders with ranges preset to the minimum and maximum values for that column. Users can pass a custom dictionary for handling specific types of data, where each key is the column in the DataFrame and the value is the streamlit widget type.

Sample of a custom dictionary:

create_data = {"Name": "text",
                "Sex": "multiselect",
                "Embarked": "multiselect",
                "Ticket": "text",
                "Pclass": "multiselect"}

The current version only supports: text, multiselect, and select.

Installation

1. First, install Streamlit

pip install streamlit

2. Next, install Pandas

pip install pandas

3. Install Streamlit Pandas

pip install streamlit-pandas

Usage

import streamlit as st
import pandas as pd
import streamlit_pandas as sp

@st.cache(allow_output_mutation=True)
def load_data():
    df = pd.read_csv(file)
    return df

file = "../data/titanic.csv"
df = load_data()
create_data = {"Name": "text",
                "Sex": "multiselect",
                "Embarked": "multiselect",
                "Ticket": "text",
                "Pclass": "multiselect"}

all_widgets = sp.create_widgets(df, create_data, ignore_columns=["PassengerId"])
res = sp.filter_df(df, all_widgets)
st.title("Streamlit AutoPandas")
st.header("Original DataFrame")
st.write(df)

st.header("Result DataFrame")
st.write(res)

This will generate the following application:
