How can I program this algorithm with Python

You are missing a close parenthesis (')') at the end of line 38. It looks like you have one missing at the end of line 39 as well. When you have a syntax error, always check the line before if the line in the error seems fine. And in the future please post the full text of the error message. That would have saved me trying to find which line the error was for.
