title: (Pygame) Python says "invalid syntax" on a " : ", but only in a specific script
body: <p>First of all, I apologize for what is probably a VERY noob question.</p>
  
  <p>That being said, I would like to understand why Python sometimes target a ":" in a script and throws the "invalid syntax" error. It usually happens after I add some stuff to the script, and then it keeps saying that putting a ":" after an "if" statment is wrong.</p>
  
  <p>To verify how this happens, I created a different "if" statment to put in the place in which the old one was, and the error still happened. I also tried to copy-paste the "if" statment in another script, and it worked.</p>
