That means you have a syntax error in one of the graded function blocks. Did you add any blank lines or change the indentation in the first few lines of any of the graded cells?

No. Nothing like that . Please help

Try saving your notebook as a new file, then download a fresh copy of the otebook. Then you can compare the two and see what got modified.
