This program is my attempt at making a more comprehensive LaTeX syntax/error checker, rather than what is printed when running other LaTeX PDF complilation terminal programs.
In pdflatex's case, given this empty LaTeX file test.tex:
\documentclass{article}
\usepackage{hyperref}
\title{Test}
\author{Hussein Esmail}
\date{\today}
\begin{document}
\maketitle
\tableofcontents
\section{First Section}
Some random sentence here.
\end{document}
When compiled (by typing pdflatex test.tex in Terminal),
it gives this output:
This is pdfTeX, Version 3.14159265-2.6-1.40.21 (TeX Live 2020) (preloaded format=pdflatex)
restricted \write18 enabled.

Simply run python3 latex_check.py <filename> in your Terminal. If the Python
file is not in the same path as the LaTeX file, put the full path (if the path
has spaces, put the whole path in quotation marks).
