Handcalcs on Streamlit

Because streamlit can render Latex code, you can use the handcalcs decorator with streamlit widgets to dynamically render Latex calculations.

This example can be found in the Examples directory in the repo.

Code:

from math import sqrt
from handcalcs.handcalcs import handcalc
import streamlit as st

@handcalc
def quadratic(a,b,c):
    x_1 = (-b + sqrt(b**2 - 4*a*c)) / (2*a)
    x_2 = (-b - sqrt(b**2 - 4*a*c)) / (2*a)
    return locals()

a = st.slider("Value for a:", 1,5, 5)
b = st.slider("Value for b:", -10, 10, -5)
c = st.slider("Value for c:", -20,0, -5)

st.write("Quadratic equation in x:")
st.latex(f"{a}x^2 + {b}x + {c} = 0")

latex_code, vals = quadratic(a,b,c)
st.latex(latex_code)
st.write("Vals from returned dict:")
st.write("x_1:", vals["x_1"], "x_2:", vals["x_2"])
