I Connected to a Crypto Exchange API in 3 Lines of Python

I needed to connect to a crypto exchange to build a trading bot. APIs sounded intimidating. Then I installed one Python library and got my balance in three lines. Getting from there to placing actual orders wasn't much harder. Here's the whole path — from creating an account to placing your first order in Python. Including every mistake I made along the way. What's an API Key, Anyway? It's a password that lets your code talk to the exchange directly, without logging into the website. You hand this key to your Python script, and suddenly your code can check balances, pull price data, and place orders. Why bother? Because manual trading means staring at charts 24/7.
