[issue45218] cmath.log has an invalid signature

[Mark Dickinson]

Mark Dickinson <dickinsm at gmail.com> added the comment:

Issue #43067 is similar. I'm not sure what the best solution is in this case:

- un-argument-clinic cmath.log, and document the signature using two lines (similar to range):

     log(z)
     log(z, base)

- change the behaviour of cmath.log so that the second argument is allowed be None (and defaults to None)
