HandCalcs modulePython

HandCalcs is a Python module that automatically generates Latex reports from Python code with minimal coding effort. HandCalcs uses Python's symbolic mathematics library to track calculation history and convert it into LaTeX code. It can be used to automatically generate mathematical equations in LaTeX format. This module is a must-have tool for any Python developer who regularly uses LaTeX for technical documentation.

grammar

To install HandCalcs, use the following command in the terminal or command prompt −

!pip install handcalcs

To use HandCalcs in your Python code, first import the handcalcs.render function. This function is used to create a LaTeX report from Python code. First, create a cell with the Python code you want to use, along with any relevant LaTeX commands, and then run the handcalcs.render function.

Algorithm

• Define your mathematical expression using standard Python syntax. You can use variables, functions, and mathematical operators such as addition, subtraction, multiplication, and division.

• Put your math expression into a Handcalcs cell, surrounding it with three curly brackets (i.e. {{{}}}).

• Use Handcalcs' rendering functions to create reports containing handwriting-style calculations. For example, you can use the code "handcalcs_rendering('report_name.tex', 'report_template.tex')" to create a report named "report_name" using a LaTeX template file named "report_template".

• Use a LaTeX compiler (such as TeX Live or MiKTeX) to compile the LaTeX report and generate the final PDF report.

• Review and refine reports as needed, making adjustments to code and templates until desired report format is achieved.

Code

import handcalcs.render

Run the following in the next Jupyter Cell.

Example 1

%%render
a = Symbol('a')
b = Symbol('b')

x = a + b
y = a * b
z = x**2 - y**2

Explanation

is:

Explanation

This example shows how symbolic math calculations on variables can be carried out using HandCalcs. The two variables a and b are defined, and the variables x and y are created through addition and multiplication processes. The third variable, z, which is the outcome of a more difficult algebraic equation, is then calculated using x and y.

Output

The Chinese translation of

Example 2

Example 2

%%render
a = Symbol('a')
b = Symbol('b')
c = Symbol('c')

result= (a**2 + b**2 + c**2)/(a**2 + b**2 - c**2)

The Chinese translation of

Explanation

is:

Explanation

The three variables a, b, and c are defined here as well and are used to compute an outcome. The final step involves using HandCalcs to show the expression in LaTeX style.

Output

Example 3

%%render
A = MatrixSymbol('A', 2, 2)
B = MatrixSymbol('B', 2, 2)
C = MatrixSymbol('C', 2, 2)

result = (A*B + B*C + C*A)**2

Explanation

This exercise demonstrates how to use HandCalcs to manipulate matrices symbolically. Three matrix factors A, B and C are defined and used to calculate the results and display the final equation in LaTeX style.

Explanation

This illustration shows how to use HandCalcs to carry out fundamental numerical arithmetic tasks. It sets the three variables a, b, and c and applies mathematical operations to determine the resultant number c

in conclusion

We explored the HandCalcs module in Python and its various features. We learned how to install HandCalcs, import the handcalcs.render function, and define HandCalc functions using the @handcalc decorator. We then created a sample script that showcases some of the main functions of HandCalcs. Overall, HandCalcs is a powerful tool for anyone who frequently uses LaTeX for technical documentation. With HandCalcs, you can automate the generation of mathematical equations and simplify the process of creating technical reports and documentation.
