A python package which helps calculate grades for a course.

Project description



This python package calculates grades for a course. The package allows users to customize their own course information with self-defined course component names, to update grades for different course components, and even understand how well the final exam needs to be to pass the course or achieve a target final grade.


This package contains the following functions:

  • construct_course: Allow users to input the information for one course component (for example, assignment name and corresponding weight) one by one. Saves the course information as a .csv file to the specified file path. (Note: any user self-defined course component name(s) can be accepted)

    • Note: Since this function accepts user interaction input when calling the function, developer team had not yet found a way to pass the function unit test through pytest.
      The unit test scenarios covered in the test_construct_course() is based on the assumption that the input .csv file is successfully generated through a local testing by calling construct_course('dsci524', '/') for example
  • update_grades: Allow users to update course component grade(s) by loading a certain saved course .csv file. The function can then save the updated course information as a new .csv file to the specified file path.

  • predict_final: Calculate how well the final exam has to be in order to pass the course or achieve a certain grade just before the final exam (for the scenario only when the final grade is missing), based on the provided other course component information.

  • calculate_grade: When all course components are presented, calculate the course overall grade based on information provided.

Suitability within Python Ecosystem

This course grade calculator is unique as it provides an interactive way for users to input the course component information and update information as needed. With the predict_final function available, users can understand how well the final exam has to be in order to pass the course or achieve a certain level of grade in this course, then adjust their final review plans based on our calculation, to meet the course expectation.

The package predict_final function does not take any users' previous study or course information into account to calculation of the desired final performance, only based on the current course component information inputted/updated.

There are other course grade calculators in the Python ecosystem. Some of the examples can be found here and here. While other packages focus on auto-grading without user interaction and they do not provide similar functions like predict_final function in this package.


$ pip install gradecalculatorpy


$ pip install --upgrade gradecalculatorpy


Please see the following Jupyter Notebook for a full walk-through of how to use gradecalculatorpy.

# import statements 
from gradecalculatorpy.construct_course import construct_course
from gradecalculatorpy.update_grades import update_assignment_grade
from gradecalculatorpy.calculate_grade import calculate_grade
from gradecalculatorpy.predict_final import predict_final
import pandas as pd

# create the grading structure of a course (follow the prompts that show up on the screen)
construct_course('dsci524', '/')

# update the grade of one component 
update_assignment_grade('dsci524.csv', 'Milestone 1', 95.25)

# find the grade needed for the final assignment if you want a target grade of 93 for the course 
predict_final('/dsci524.csv', 93)

# calculate the final grade of the course 


Please see our official documentation on Read the Docs here.

Acknowledging the use of OS

Since Windows and Mac systems have different file path naming style and we run all our pytest successfully on Mac. Therefore, we highly recommend the TA grading this assignment using Mac.
