HandCalcs Module Python
HandCalcs is a Python library that automatically generates LaTeX-formatted mathematical equations from Python calculations. It creates beautiful, hand-written-style mathematical documentation directly from your Python code, making it essential for technical reports and scientific documentation.
Installation
Install HandCalcs using pip ?
pip install handcalcs
Basic Usage
HandCalcs works primarily in Jupyter notebooks using the %%render magic command. Import the library and use the decorator to render calculations ?
import handcalcs.render
Example 1: Basic Arithmetic
This example demonstrates simple numerical calculations with automatic LaTeX rendering ?
%%render a = 2 b = 3 c = 2*a + b/3
This code assigns values to variables and performs arithmetic operations. HandCalcs automatically shows both the calculation steps and final result in LaTeX format.
Example 2: Symbolic Mathematics
HandCalcs works with SymPy symbols for algebraic expressions ?
%%render
from sympy import Symbol
a = Symbol('a')
b = Symbol('b')
x = a + b
y = a * b
z = x**2 - y**2
This creates symbolic variables and performs algebraic operations. The output shows the mathematical relationships in proper mathematical notation.
Example 3: Complex Expressions
Demonstrate more complex mathematical expressions ?
%%render
from sympy import Symbol
a = Symbol('a')
b = Symbol('b')
c = Symbol('c')
result = (a**2 + b**2 + c**2)/(a**2 + b**2 - c**2)
This example shows how HandCalcs handles fractions and polynomial expressions in proper mathematical notation.
Example 4: Matrix Operations
HandCalcs also supports matrix symbolic operations ?
%%render
from sympy import MatrixSymbol
A = MatrixSymbol('A', 2, 2)
B = MatrixSymbol('B', 2, 2)
C = MatrixSymbol('C', 2, 2)
result = (A*B + B*C + C*A)**2
This demonstrates matrix multiplication and addition with proper mathematical formatting for matrices.
Key Features
