) class, likewise inherited from birds. When you create a Oriole object, the object automatically owns the bird's properties.Through the inheritance system, we can reduce the duplication of information and duplicate statements in the program. If we define two classes separately and do not inherit from the birds, we must enter the birds ' attributes into the definitions of the chickens and the Oriole classes separately. The whole process becomes tedious, so object-oriented improves the reuse of

memory again. Its initial value is the number of elements the programmer originally requested. When the storage space is full and an element is added, it automatically doubles the expansion space on the original basis to store more elements. In layman's words, it is the space that has been applied. The relationship between the three is as follows.(4) Empty (): Returns True if the current vector is emptyMethods for accessing objects in vectors(1) Front (): Returns the first object in a vector.(2

;} ★ Summary to this position, the addition and subtraction algorithm of large integer is finished, the key to achieve addition and subtraction is the idea of classification, so that the complex problems can be simplified, and then conquer. The next few will focus on multiplication calculation, multiplication is more complex than addition and subtraction, and in the calculation, multiplication is time-consuming, so to do a lot of optimization work, otherwise the power multiplication will

Zip (range (1,100,2), Range (2,100,2))]2.2 List-generation with conditional filteringA list-generated for loop can also be followed by an if judgment. For example:>>> [x * x for x in range (1, 11)][1, 4, 9, 16, 25, 36, 49, 64, 81, 100]If we want even squares, without changing the range (), you can filter by if:>>> [x * x for x in range (1, one) if x% 2 = = 0][4, 16, 36, 64, 100]2.3 Nested List-generatedFor loops can be nested, so in a list build, you can also use a multi-layer for loop to gener
