Python does have a concept of "truthy" that includes meaning for not just the standard Booleans but for 0 and non-zero and the empty string and many more odd things such as an object that defines __bool__ (). But saying it returns a Boolean True/False valuesounds direct and simple and informative enough if that is True. What bothers me is the assumption that anyone knows not so muchjust group theory but what the argument to the function looks like as a Python object of some kind. Does the function accept only some permutation object managed by a specific module? Will it accept some alternate representation such as a list structure or other iterator?
That's a fair point. However, this function will be the 22nd one in a module for dealing with permutations and groups of permutations. The module has a lengthy docstring explaining the several ways provided to specify a permutation. That way, the same information doesn't need to be written twenty-plus times.
Obviously deeper details would normally be in a manual page or other documentation but as "permutations" are likely not to be what most people think about before breakfast, or even after, odd as that may seem, ...
