SyntaxError: unexpected EOF while parsing

Unexpected end of file during parsing – EOF stands for End of File.

This means your code ended prematurely – the compiler was expecting something else , but your code ended before it happened .

The usual reason is that you started something and not finished – quote, apostrophe, parenthesis (round, square, curly): "'([{.

Basically it’s ) at the end of your program.
