Programming Machine Learning:incorrect reference to datetime.format() method (p291)
Hi Paolo, thanks for what looks like a great book on this topic. Looking forward to no longer being an ML “noob”.
Just a minor error: on p291, you mention that the datetime package has a format() method, but the code snippet that follows to illustrate the usage invokes strftime() instead.
Thanks,
Richard
