a common lock, So it's possible to wake up a, that is, to wake up the code that should not be executed, which is false wakeup.So we use the while condition, and even if it wakes up, we do a conditional interpretation, so that the code that is falsely awakened will wait again.This requires the programmer to control the error of avoiding false wakes. and lock and condition to help us solve this problem. There can be more than one condition inside a lock. So the same lock can be implemented in mul

(up Transformation)principle: when a super (parent) class object references a variable that references a subclass object, the type of the referenced object rather than the type of the reference variable determines which member method to call (that is, the method by which the subclass object's type determines who is called ).But the method that is called must be defined in the superclass, that is, the method covered by the quilt class.-------------------------------------------------------------

Python learns Day 9 property multi-inheritance Mixin, pythonmixin When binding an attribute, If we expose the attribute directly, although it is easy to write, but we cannot check the parameter, so we can change the score as needed: s = Student()s.score = 9999 To limit the score range, you can use the set_score () method to set the score and get_score () to obtain the score. In this way, in the set_score ()
