Simple CLI program to calculate GPA, with support for some queries.
calcgpa.py [-h] [-y YYYY] [-ub 0-100] [-lb 0-100] [-s A|B|C] datafile
-his for displaying help-yis for selecting courses of a specific year, e.g:-y 2018-sis for selecting courses of a specific semester, e.g:-s A-ub&lbis for selecting courses whose grades are withing a specific range, e.g. :-lb 70 -ub 100means the grade should be above 70 & below 100datafilecontains the info about the courses (most importantly, their grades).
The program scans the datafile, filters some courses according to the specified query, then prints the filtered courses and the calculated GPA in a pretty format.
Short example for the contents of datafile:
Sem | Course ID | Pts | Course Name | Grade
______|___________|_____|____________________________________|______
2018B | 0368-1118 | 6 | Discrete Math | 98
------|-----------|-----|------------------------------------|------
2019A | 0368-1105 | 6 | Extended Intro To Computer Science | 67
2019B | 0366-1111 | 7 | Linear Algebra 1a | 100
------|-----------|-----|------------------------------------|------
2020A | 0366-1101 | 7 | Calculus 1a | 78
2020A | 0368-2157 | 4 | Software 1 | 89
2020B | 0366-2010 | 5 | Intro To Probability | ???
2020B | 0368-2158 | 4 | Data Structures | ???
This example makes use of the program's ignore policy: In detail, the 1st line of the input file is always ignored, and so is every line that begins with '_', '-' or '#'. courses with grade value ??? will also be ignored.
Therefore, the following datafile contents, albeit less pretty, are parsed equivalently to the previous example:
# first line is ignored
2018B|0368-1118|6|DiscreteMath|98
2019A|0368-1105|6|ExtendedIntroToComputerScience|67
2019B|0366-1111|7|LinearAlgebra1a|100
2020A|0366-1101|7|Calculus1a|78
2020A|0368-2157|4|Software1|89
2020B|0366-2010|5|IntroToProbability|???
2020B|0368-2158|4|DataStructures|???
for the above datafile contents:
