lambda expression python

A lambda expression in C # is the evolution of an anonymous method in C # 2, so you start by simplifying the way you do it from an anonymous function.The example is to get a string parameter and then return an int.First, the anonymous method is written as follows:FuncThe most verbose form of a lambda expression is:(Exp

This is mainly for programmers who have studied C # 2.0, if they already know what an anonymous method is. If it is not clear, please read "Serial: C # 2.0 Primer" (This will be translated in the future). OK, let's get to the point. A lambda expression (a lambda expression), interpreted in one sentence, is (not very

Delegate to anonymous method to lambda expression, lambda expression What is Delegation In a typical example, when the whole of a method is relatively fixed and a small part has changed, sometimes our common practice is: upload a variable to the method. The method determines the specific execution of these changes base
