The pandas API leverages these strengths of Python, providing robust capabilities for data manipulation and analysis. Functions such as str methods for string operations and support for custom lambda functions enable users to write expressive algorithms directly within their workflows. Python’s compatibil...
这些称为lambda表达式的目标类型,可以用作返回类型,或lambda目标代码的参数。例如,若一个方法接收Runnable、Comparable或者 Callable 接口,都有单个抽象方法,可以传入lambda表达式。类似的,如果一个方法接受声明于 java.util.function 包内的接口,例如 Predicate、Function、Consumer 或 Supplier,那么可以向其传lambda表达式。
AWS Lambda functions are a small piece of a program that carries out a specific task. An AWS resource, such as an Amazon S3 bucket, is created. Then a Lambda function and a Lambda trigger are created. When objects are added to or removed from the bucket, it invokes the function and ou...

in the same line, the Python interpreter creates a new object, then references the second variable at the same time. If you do it on separate lines, it doesn't "know" that there's already "wtf!" as an object (because "wtf!" is not implicitly interned as per the facts mentioned abov...
