such as generators can also return values through the yield statement and suspend their state so that they can later recover state, which is a high-level concept. Global declares a module-level variable and is assigned a value. by default, all objects that are assigned to a function are local variables of the function and exist only during the run of the function. In order to assign a variable name that can be used throughout the module, the function needs to be enumerated in the global sta

) Remove the print statement and add the print () function to achieve the same functionality.

Chapter Content anonymous function lambda anonymous function application One, anonymous function lambdaWhat we call an anonymous function is lambda, what is lambda?A lambda is an expression, not a statement, so it can appear where the DEF statement cannot occur, and does not require the name of the function to be specified; Lambda expressions can also improve code readability and simplify codeLambda expressions are primarily used to write simple methods that are good for comple

1. The dashed box represents the abstract class, and the names of a large number of classes in the diagram begin with abstract, and they are simply tools that partially implement a particular interface, so you can choose to inherit from abstract when you create it.A practical approach in collections: Pick a few frequently used:1. Reverse (List): Reversal order2. Rotate (list,int distance) all elements move backwards distance positions, looping the end elements to the front (three times reverse)3
