recursive function python

I. Lambda anonymous function (one line for a function, but not a complex function operation)Syntax: function name = lambda parameter: return valueAttention:1. Functions can have more than one argument, separated by commas2. Anonymous functions no matter how complex, can only write one line, and the logic is finished di
