"Python," Leo said. "From zero to hero."

In the spring of 2020, Leo Mendoza stared at his laptop screen, feeling like a ghost in a machine. He was a logistics coordinator for a small shipping company, and spreadsheets had become his prison. Every day, the same ritual: copy, paste, filter, email. Copy, paste, filter, email.

He didn't say "curso." But the course was still open on his second monitor—the last lecture, titled "Congratulations! You Made It."

Leo opened his laptop. He wrote a script in twenty minutes—using pandas to merge three CSV exports, datetime to estimate transit times, and smtplib to send batch email updates to customers.

But the pandemic had emptied the streets and filled the silence with uncertainty. With extra hours at home, he finally caved and searched for help. That’s when he found it: — a course with thousands of five-star reviews, a cartoon snake on the cover, and a promise that anyone could learn.
