I was running my program just fine. However, today an error occurs "ValueError: invalid literal for int() with base 10: "

I'm very confused and don't know where it went wrong.

  Hi Jingyue,

  This is a Python error message indicating that you are trying to convert the empty string \(\texttt{''}\) to an int.

  You should check the values of your table before converting them.

  Cheers,
  Matthias
