Python output problem

I’m getting ‘None’ at the end of the output. Why is this happening?

difficult to say without seeing the code. The link is exercise specific, then checks for logged in user, and then load that users code. So clicking on the link will show my version of the project, not yours

please copy paste your code to the forum

most logic answer: you do print(function_call()) somewhere, where function_call is a function that doesn’t return anything, result in None (the absence of a return value)
