Python isn't just a programming language-it's the engine behind many of the digital tools and platforms we use daily. Think of it like the electricity that powers our homes-essential, often unseen, and remarkably flexible. If you've ever used Instagram, browsed YouTube, or checked Dropbox, you've interacted with software built using Python.

Ask anyone who was scheduled to fly in or out of London Heathrow airport in the UK on March 20 and 21 2025, and they'll tell you that disruption to critical national infrastructure (CNI) is no joke. A fire at a local electricity substation resulted in thousands of journey disruptions and cancellations as one of the world's busiest airports was closed and incoming planes were diverted to alternative locations. The knock-on effect of the closure continued for days, and lost tourism revenue for the UK.
