We all have those defining moments in our career or our education that made us realize that we wanted to become devs.
For me, it was in my first programming class when I wrote some Python code that added a couple of numbers together. It wasn't like a calculator or anything, it was literally:
print 3 + 4
It sounds dumb, but when I ran that one line in Idle I said to myself "I made the computer do that... Whoa".
What was your dev-defining moment?
