debugging lambda functions

Anonymous functions: Lambda expressions, anonymous methods, and lambda expressions An "inline" statement or expression of an anonymous function, which can be used wherever the delegate type is required. You can use an anonymous function to initialize the name delegate, or pass the name delegate (instead of the name delegate type) as the method parameter. There ar

Lambda functions Python supports an interesting syntax that allows you to quickly define the smallest function of a single line. These functions, called Lambda, are borrowed from Lisp and can be used wherever a function is needed. def f (x): Return x*2, using a lambda func

A brief introduction to lambda anonymous functions in Python. For more information, see lambda functions. Let's take a look at the simplest example: The code is as follows: Def f (x ):Return x ** 2Print f (4) If lambda is used in Python, it is written as follows: The cod

points: 1. When using Python to write some execution scripts, using lambda can save the process of defining functions and simplify the code. 2. For some abstract functions that will not be reused elsewhere, it is also difficult to give them a name. You do not need to consider naming when using lambda. 3. Use

The first section, the collection In addition to the previously learned data types, int,str,bool,list,dict,tuple, there is also a basic data type-collection, which is a set of unordered, non-repeating sequences. Because of this feature, the elements of the collection can also be used as keys to the dictionary.1. Creation of collectionsCast = set () #创建空集合2. Operation of the collectionAdd () #一次只能添加一个元素Update () #一次能添加多个元素Clear () #清空一个集合Copy () #拷贝一个集合Difference () #比较两个集合, generates a new col
