The reduce() function in Python takes in a function and a list as argument. The function is called with a lambda function and a list and a new reduced result is returned. This performs a repetitive operation over the pairs of the list. This is a part of functools module. Example: 注意...

lambda 函数的语法是lambda args: expression。你首先编写单词lambda,然后是一个空格,然后是所有参数的逗号分隔列表,后跟一个冒号,然后是作为函数体的表达式。 请注意,你不能为 lambda 函数命名,因为它们根据定义是匿名的(没有名称)。 一个lambda 函数可以有你需要使用的任意数量的参数,但主体必须是一个单一的表达式。
