I have added values to the parameters (length = "16, nums = “1”, etc) I am not sure why this is not passing.

Hello @mjb2024

In the request it says:

Modify your function declaration to take default parameters. Use 16 for the length and 1 for the other constraints.

Perhaps it is not clear that those values are not strings but integers. What’s the difference? The quotes.
Also, in Python it is considered best practice not to place spaces between variable names and values in function arguments.
Instead of this (var = 1) do (var=1)
