Not Python, but Ruby and HTML/CSS/JS examples: I worked at an international company with its own terrible email marketing system. I wrote my own email builder based on their templates that allowed me to visually build emails and then just copy and paste in the code! I also wrote a Ruby script that iterated over a CSV/Excel spreadsheet file supplied on a regular basis to generate HTML page, which I then pasted into their horrible CMS! The previous person in my job used to have to do all those things manually and it took forever! The key win for me was convincing the head of IT to enable WSL on my work supplied Windows 10 Laptop! Having access to Linux made everything possible!
