Throwing error

[parthi2929]

Hi

I tried using your bookbook, but I am getting error as below. could not understand what is going wrong. I had simplified my file names as required.

Any idea why this appear? Below is my current directory from where I run the command.

Bookbook expects filenames beginning with a number and a dash, like 1-intro.ipynb. The error message could be clearer about that.

Ok It already has "121 - xxx". I had 121 for a reason. The space in between was a problem?

Yup, it expects it without a space. The requirement could be relaxed, it's just a fairly quick implementation.
