Syntax errors happen when you write code that breaks the expected rules. In this case, we wrote our code in plain English, but the interpreter doesn't understand English, only Python. Let's try this again. This time, we'll take two plus two, and just like that, we get four. That's because two plus two is a valid Python expression. Let's try another one. Two plus, and then enter.
