unexpected EOF while parsing (python)

Question

what does it mean?

Answer 1

End Of File.

Answer 2

The SyntaxError: unexpected EOF while parsing means that the end of your source code was reached before all code blocks were completed. A Python code block starts with a statement like for i in range(100): and requires at least one line afterwards that contains code that should be in it.

Also, this can simply mean you are missing or have too many parenthesis. For example this has too many, and will result in unexpected EOF.
