Answer 3

答案就在下面一页：

The range really is 0 to 61; according to the Posix standard this accounts for leap seconds and the (very rare) double leap seconds. The time module may produce and does accept leap seconds since it is based on the Posix standard, but the datetime module does not accept leap seconds in strptime() input nor will it produce them in strftime() output.
