example, finding the value of "irrational π" and calculating "fixed points. In this case, it is better to use the probability algorithm to solve the problem. Iii. Example In the numerical probability, the most typical question is "computing definite points". Set f (x) = 1-x2 to calculate the definite point: I = 1000001 (1-x2) dx value. Analysis: Step 1: plot the Coordinate Map of the function f (x) = 1-x2 in: Step 2: If we randomly place a vertex into the rectangle, the probability

Microsoft released the Windows 8 App Store 1. Win8 App Store Microsoft provides all developers with an App Store to upload Win8 applications. The specific splitting method seems to be 37 points, and there are some discounts for developers.

about __slots__ is that it can be used as an encapsulation tool to prevent users from adding new properties to an instance. Although the use of __slots__ can achieve this goal, but this is not its original intention. More is used as a memory optimizer tool.Four. Demonstration of how to use __slots__.Example 1:Class Foo:__slots__= ' x 'F1=foo ()F1.x=1f1.y=2# ErrorPrint (f1.__slots__) #f1不再有__dict__Class Bar:__slots__=[' x ', ' Y ']N=bar ()n.x,n.y=1,2n.z=3# ErrorExample 2: (Validation of __slots_
