invalid syntax

[DewDropTales]

Hello I get this error and can't seem to fix it I saw someone else with the same error and someone gave a solution but it doesn't work for me. I have all the right files and folders and it still doesn't work.

This is my error: File "amiiboconvert.py", line 20 def write_output(name: str, assemble: str, out_dir: str): ^ SyntaxError: invalid syntax
