Installation

The project can be install via pip

pip install mathgenerator

Basic Usage

Here is an example of how you would generate an addition problem:

from mathgenerator import mathgen

#generate an addition problem
problem, solution = mathgen.addition()

#another way to generate an addition problem using genById()
problem, solution = mathgen.genById(0)

Creating a worksheet

If you wish to create a worksheet, you can use the worksheetgen package. Install this with pip install worksheetgen. Here is an example of how a worksheet would be generated.

from mathgenerator import mathgen
from worksheetgen.wg import Worksheet

worksheet = Worksheet("Worksheet title")
worksheet.add_instruction("Instructions")
# Writes 10 problems generated with id 1, [0] at the end specifies to take problem, and not solution.
for _ in range(10):
	worksheet.add_problem(mathgen.genById(1)[0])
worksheet.write_pdf()

This creates the pdf ws.pdf in your current directory

Documentation

• getGenList() returns a list of all generators in the repository in the format [id, title, self, funcname, subjectname]

• genById(id) generates a problem, solution set with generator id id in the format [problem, solution]

• Pass the kwarg format=latex to return problem and solution set as latex. If latex is not available for that generator, the problem will return the string "Latex unavailable"

• Pass the kwarg format=raw to return just the raw data for each generator. An array of each variable necessary to the generator is returned.
